•
•
•
The OPA330 series of CMOS operational amplifiers
offer precision performance at a very competitive
price. These devices are members of the Zero-Drift
family of amplifiers which use a proprietary autocalibration technique to simultaneously provide low
offset voltage (50-μV maximum) and near-zero drift
over time and temperature at only 35 μA (maximum)
of quiescent current. The OPA330 family features railto-rail input and output in addition to near-flat 1/f
noise, making this amplifier ideal for many
applications and much easier to design into a system.
These devices are optimized for low-voltage
operation as low as 1.8 V (±0.9 V) and up to 5.5 V
(±2.75 V).

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should
be current limited to 10 mA or less.

8 Detailed Description
8.1 Overview
The OPA330 family of Zerø-Drift amplifiers feature a proprietary auto-calibration technique to simultaneously
achieve near-zero drift over time and temperature at only 35 µA (maximum) of quiescent current while also
providing low offset voltage (50 µV maximum). These devices are unity-gain stable, precision operational
amplifiers free from unexpected output and phase reversal. The OPA330 series are also optimized for lowvoltage, single-supply operation: as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V).
The proprietary Zerø-Drift circuitry lowers the 1/f noise component as well as offers the advantage of low input
offset voltage over time and temperature. The OPA330 series of operational amplifiers are ideal for cost-sensitive
applications and applications that operate without regulation directly from battery power.

8.3 Feature Description
The OPA33x family is unity-gain stable and free from unexpected output phase reversal. These devices use
a proprietary auto-calibration technique to provide low offset voltage and very low drift over time and
temperature. For lowest offset voltage and precision performance, optimize circuit layout, and mechanical
conditions. Avoid temperature gradients that create thermoelectric (Seebeck) effects in the thermocouple
junctions formed from connecting dissimilar conductors. Cancel these thermally-generated potentials by
assuring they are equal on both input terminals. Other layout and design considerations include:
• Use low thermoelectric-coefficient conditions (avoid dissimilar metals).
• Thermally isolate components from power supplies or other heat sources.
• Shield operational amplifier and input circuitry from air currents, such as cooling fans.
Following these guidelines reduces the likelihood of junctions being at different temperatures, which can
cause thermoelectric voltage drift of 0.1 µV/°C or higher, depending on materials used.
8.4 Device Functional Modes
The OPAx330 has a single functional mode and is operational when the power-supply voltage is greater than
1.8 V (±0.9 V). The maximum power-supply voltage for the OPAx330 is 5.5 V (±2.75 V).

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The OPA330, OPA2330, and OPA4330 are unity-gain stable, precision operational amplifiers free from
unexpected output and phase reversal. The use of proprietary Zerø-Drift circuitry gives the benefit of low input
offset voltage over time and temperature, as well as lowering the 1/f noise component. As a result of the high
PSRR, these devices work well in applications that run directly from battery power without regulation. The
OPA330 family is optimized for low-voltage, single-supply operation. These miniature, high-precision, low
quiescent current amplifiers offer high-impedance inputs that have a common-mode range 100 mV beyond the
supplies and a rail-to-rail output that swings within 100 mV of the supplies under normal test conditions. The
OPA330 series are precision amplifiers for cost-sensitive applications.
9.1.1 Operating Voltage
The OPA330 series operational amplifiers can be used with single or dual supplies from an operating range of
VS = 1.8 V (±0.9 V) up to 5.5 V (±2.75 V). Supply voltages greater than 7 V can permanently damage the device
(see Absolute Maximum Ratings). Key parameters that vary over the supply voltage or temperature range are
shown in Typical Characteristics.
9.1.2 Input Voltage
The OPA330, OPA2330, and OPA4330 input common-mode voltage range extends 0.1 V beyond the supply
rails. The OPA330 is designed to cover the full range without the troublesome transition region found in some
other rail-to-rail amplifiers.
Typically, input bias current is approximately 200 pA. Input voltages exceeding the power supplies however, can
cause excessive current to flow into or out of the input pins. Momentary voltages greater than the power supply
can be tolerated if the input current is limited to 10 mA. This limitation is easily accomplished with an input
resistor, as shown in Figure 18.

Figure 18. Input Current Protection
9.1.3 Input Differential Voltage
The typical input bias current of the OPA330 during normal operation is approximately 200 pA. In over-driven
conditions, the bias current can increase significantly (see Figure 17). The most common cause of an over-driven
condition occurs when the operational amplifier is outside of the linear range of operation. When the output of the
operational amplifier is driven to one of the supply rails the feedback loop requirements cannot be satisfied and a
differential input voltage develops across the input pins. This differential input voltage results in activation of
parasitic diodes inside the front end input chopping switches that combine with 10-kΩ electromagnetic
interference (EMI) filter resistors to create the equivalent circuit illustrated in Figure 19. Notice that the input bias
current remains within specification within the linear region.

9.1.4 Internal Offset Correction
The OPA330, OPA2330, and OPA4330 operational amplifiers use an auto-calibration technique with a timecontinuous, 125-kHz operational amplifier in the signal path. This amplifier is zero-corrected every 8 µs using a
proprietary technique. Upon power up, the amplifier requires approximately 100 µs to achieve specified VOS
accuracy. This design has no aliasing or flicker noise.
9.1.5 EMI Susceptibility and Input Filtering
Operational amplifiers vary in their susceptibility to EMI. If conducted EMI enters the operational amplifier, the DC
offset observed at the amplifier output may shift from its nominal value while the EMI is present. This shift is a
result of signal rectification associated with the internal semiconductor junctions. While all operational amplifier
pin functions can be affected by EMI, the input pins are likely to be the most susceptible. The OPA330
operational amplifier family incorporates an internal input low-pass filter that reduces the amplifier response to
EMI. Both common-mode and differential mode filtering are provided by the input filter. The filter is designed for a
cutoff frequency of approximately 8 MHz (–3 dB), with a rolloff of 20 dB per decade.
9.1.6 Achieving Output Swing to the Operational Amplifier Negative Rail
Some applications require output voltage swings from 0 V to a positive full-scale voltage (such as 2.5 V) with
excellent accuracy. With most single-supply operational amplifiers, problems arise when the output signal
approaches 0 V, near the lower output swing limit of a single-supply operational amplifier. A good single-supply
operational amplifier may swing close to single-supply ground, but does not reach ground. The output of the
OPA330, OPA2330, and OPA4330 can be made to swing to ground, or slightly below, on a single-supply power
source. To do so requires the use of another resistor and an additional, more negative, power supply than the
operational amplifier negative supply. A pulldown resistor may be connected between the output and the
additional negative supply to pull the output down below the value that the output would otherwise achieve, as
shown in Figure 20.

SBOS432G – AUGUST 2008 – REVISED AUGUST 2016
Application Information (continued)
The OPA330, OPA2330, and OPA4330 have an output stage that allows the output voltage to be pulled to its
negative supply rail, or slightly below, using the technique previously described. This technique only works with
some types of output stages. The OPA330, OPA2330, and OPA4330 have been characterized to perform with
this technique; the recommended resistor value is approximately 20 kΩ. This configuration increases the current
consumption by several hundreds of microamps. Accuracy is excellent down to 0 V and as low as –2 mV.
Limiting and nonlinearity occur below –2 mV, but excellent accuracy returns as the output is again driven above
–2 mV. Lowering the resistance of the pulldown resistor allows the operational amplifier to swing even further
below the negative rail. Resistances as low as 10 kΩ can be used to achieve excellent accuracy down to
–10 mV.
9.1.7 Photosensitivity
Although the OPA330 YFF package has a protective backside coating that reduces the amount of light exposure
on the die, unless fully shielded, ambient light can reach the active region of the device. Input bias current for the
package is specified in the absence of light. Depending on the amount of light exposure in a given application, an
increase in bias current, and possible increases in offset voltage should be expected. Fluorescent lighting may
introduce noise or hum because of the time-varying light output. Best layout practices include end-product
packaging that provides shielding from possible light sources during operation.
9.2 Typical Application
9.2.1 Bidirectional Current-Sensing
This single-supply, low-side, bidirectional current-sensing solution detects load currents from –1 A to 1 A. The
single-ended output spans from 110 mV to 3.19 V. This design uses the OPA2330 because of its low offset
voltage and rail-to-rail input and output. One of the amplifiers is configured as a difference amplifier and the other
provides the reference voltage.

9.2.1.1 Design Requirements
This solution has the following requirements:
• Supply voltage: 3.3 V
• Input: –1 A to 1 A
• Output: 1.65 V ±1.54 V (110 mV to 3.19 V)
9.2.1.2 Detailed Design Procedure
The load current, ILOAD, flows through the shunt resistor (RSHUNT) to develop the shunt voltage, VSHUNT. The shunt
voltage is then amplified by the difference amplifier, which consists of U1A and R1 through R4. The gain of the
difference amplifier is set by the ratio of R4 to R3. To minimize errors, set R2 = R4 and R1 = R3. The reference
voltage, VREF, is supplied by buffering a resistor divider using U1B. The transfer function is given by Equation 1.
VOUT = VSHUNT ´ GainDiff_Amp + VREF
where
•
•
VSHUNT = ILOAD ´ RSHUNT

VREF = VCC ´

(1)
There are two types of errors in this design: offset and gain. Gain errors are introduced by the tolerance of the
shunt resistor and the ratios of R4 to R3 and, similarly, R2 to R1. Offset errors are introduced by the voltage
divider (R5 and R6) and how closely the ratio of R4/R3 matches R2/R1. The latter value impacts the CMRR of the
difference amplifier, which ultimately translates to an offset error.
Because this is a low-side measurement, the value of VSHUNT is the ground potential for the system load.
Therefore, it is important to place a maximum value on VSHUNT. In this design, the maximum value for VSHUNT is
set to 100 mV. Equation 2 calculates the maximum value of the shunt resistor given a maximum shunt voltage of
100 mV and maximum load current of 1 A.
V
RSHUNT(Max) = SHUNT(Max) = 100 mV = 100 mW
ILOAD(Max)
1A
(2)
The tolerance of RSHUNT is directly proportional to cost. For this design, a shunt resistor with a tolerance of 0.5%
was selected. If greater accuracy is required, select a 0.1% resistor or better.
The load current is bidirectional; therefore, the shunt voltage range is –100 mV to 100 mV. This voltage is divided
down by R1 and R2 before reaching the operational amplifier, U1A. Take care to ensure that the voltage present
at the noninverting node of U1A is within the common-mode range of the device. Therefore, it is important to use
an operational amplifier, such as the OPA330, that has a common-mode range that extends below the negative
supply voltage. Finally, to minimize offset error, note that the OPA330 has a typical offset voltage of merely
±8 µV (±50 µV maximum).
Given a symmetric load current of –1 A to 1 A, the voltage divider resistors (R5 and R6) must be equal. To be
consistent with the shunt resistor, a tolerance of 0.5% was selected. To minimize power consumption,
10-kΩ resistors were used.
To set the gain of the difference amplifier, the common-mode range and output swing of the OPA330 must be
considered. Equation 3 and Equation 4 depict the typical common-mode range and maximum output swing,
respectively, of the OPA330 given a 3.3-V supply.

Typical Application (continued)
The resistor value selected for R1 and R3 was 1 kΩ. 15.4 kΩ was selected for R2 and R4 because it is the
nearest standard value. Therefore, the ideal gain of the difference amplifier is 15.4 V/V.
The gain error of the circuit primarily depends on R1 through R4. As a result of this dependence, 0.1% resistors
were selected. This configuration reduces the likelihood that the design requires a two-point calibration. A simple
one-point calibration, if desired, removes the offset errors introduced by the 0.5% resistors.

11 Layout
11.1 Layout Guidelines
TI always recommends paying attention to good layout practice. Keep traces short and, when possible, use a
printed-circuit board (PCB) ground plane with surface-mount components placed as close to the device pins as
possible. Place a 0.1-µF capacitor closely across the supply pins. These guidelines must be applied throughout
the analog circuit to improve performance and provide benefits such as reducing the electromagnetic interference
(EMI) susceptibility.
For lowest offset voltage and precision performance, circuit layout, and mechanical conditions must be optimized.
Avoid temperature gradients that create thermoelectric (Seebeck) effects in the thermocouple junctions formed
from connecting dissimilar conductors. These thermally-generated potentials can be made to cancel by assuring
they are equal on both input terminals. Other layout and design considerations include:
• Use low thermoelectric-coefficient conditions (avoid dissimilar metals).
• Thermally isolate components from power supplies or other heat sources.
• Shield operational amplifier and input circuitry from air currents, such as cooling fans.
Following these guidelines reduces the likelihood of junctions being at different temperatures, which can cause
thermoelectric voltage drift of 0.1 µV/°C or higher, depending on materials used.
11.1.1 VQFN and SON Packages
The OPA4330 is offered in a VQFN package. The OPA2330 is available in a 8-pin SON package, which is a
VQFN package with lead contacts on only two sides of the bottom of the package. These leadless, near-chipscale packages maximize board space and enhance thermal and electrical characteristics through an exposed
pad. VQFN and SON packages are physically small, have a smaller routing area, improved thermal performance,
and improved electrical parasitics, with a pinout scheme that is consistent with other commonly-used packages,
such as SOIC and VSSOP. Additionally, the absence of external leads eliminates bent-lead issues.
The VQFN and SON package can be easily mounted using standard PCB assembly techniques. See the
application note, QFN/SON PCB Attachment (SLUA271), and the application report, Quad Flatpack No-Lead
Logic Packages (SCBA017), both available for download at www.ti.com.
NOTE
The exposed leadframe die pad on the bottom of the package should be connected to V–.
11.1.2 VQFN and SON Layout Guidelines
The leadframe die pad must be soldered to a thermal pad on the PCB. A mechanical data sheet showing an
example layout is attached at the end of this data sheet. Refinements to this layout may be required based on
assembly process requirements. Mechanical drawings located at the end of this data sheet list the physical
dimensions for the package and pad. The five holes in the landing pattern are optional, and are intended for use
with thermal vias that connect the leadframe die pad to the heat sink area on the PCB.
Soldering the exposed pad significantly improves board-level reliability during temperature cycling, key push,
package shear, and similar board-level tests. Even with applications that have low-power dissipation, the
exposed pad must be soldered to the PCB to provide structural integrity and long-term reliability.

11.1.3 OPA330 DSBGA
The OPA330 YFF package is a lead- (Pb-) free, die-level, wafer chip-scale package. Unlike devices that are in
plastic packages, these devices have no molding compound, lead frame, wire bonds, or leads. Using standard
surface-mount assembly procedures, the OPA330 YFF can be mounted to a printed-circuit board (PCB) without
additional underfill. Figure 26 and Figure 27 detail the pinout and package marking, respectively. See the
application note, NanoStar™ and NanoFree™ 300μm Solder Bump WCSP (SBVA017) for more detailed
information on package characteristics and PCB design.
