DESCRIPTION/ORDERING INFORMATION
The OPA333A series of CMOS operational amplifiers uses a proprietary auto-calibration technique to
simultaneously provide very low offset voltage (10 µV max) and near-zero drift over time and temperature. These
miniature, high-precision, low-quiescent-current amplifiers offer high-impedance inputs that have a
common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single
or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) may be used. They are optimized for
low-voltage single-supply operation.
The OPA333A family offers excellent common-mode rejection ratio (CMRR) without the crossover associated
with traditional complementary input stages. This design results in superior performance for driving
analog-to-digital converters (ADCs) without degradation of differential linearity.
The OPA333A (single version) is available in the SC70-5 and SOT23-5 packages. The OPA2333A (dual version)
is offered in the SO-8 package. All versions are specified for operation from –55°C to 125°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. 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.

Long-term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction of
overall device life. See http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.

APPLICATION INFORMATION
The OPA333A and OPA2333A are unity-gain stable and free from unexpected output phase reversal. They 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, circuit layout and mechanical conditions should 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 ensuring 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 op amp and input circuitry from air currents, such as cooling fans
Following these guidelines will reduce the likelihood of junctions being at different temperatures, which can cause
thermoelectric voltages of 0.1 µV/°C or higher, depending on materials used.
Operating Voltage
The OPA333A and OPA2333A op amps operate over a power-supply range of 1.8 V to 5.5 V (±0.9 V to
±2.75 V). Supply voltages higher than 7 V (absolute maximum) can permanently damage the device. Parameters
that vary over supply voltage or temperature are shown in the Typical Characteristics section of this data sheet.
Input Voltage
The OPA333A and OPA2333A input common-mode voltage range extends 0.1 V beyond the supply rails. The
OPA333A is designed to cover the full range without the troublesome transition region found in some other
rail-to-rail amplifiers.
Normally, input bias current is about 70 pA; however, input voltages exceeding the power supplies 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(see
Figure 1).

Internal Offset Correction
The OPA333A and OPA2333A op amps use an auto-calibration technique with a time-continuous 350-kHz op
amp 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.

Achieving Output Swing to the Op Amp 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 op amps, problems arise when the output signal approaches 0 V,
near the lower output swing limit of a single-supply op amp. A good single-supply op amp may swing close to
single-supply ground, but will not reach ground. The output of the OPA333A and OPA2333A 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 op amp 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 (see Figure 2).

Figure 2. VOUT Range to Ground
The OPA333A and OPA2333A 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 OPA333A and OPA2333A have been characterized to perform with this technique;
however, the recommended resistor value is approximately 20 kΩ. Note that this configuration will increase the
current consumption by several hundreds of microamps. Accuracy is excellent down to 0 V and as low as
–2 mV. Limiting and nonlinearity occurs 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 op amp 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.
General Layout Guidelines
Attention to good layout practices is always recommended. 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 should be applied throughout the
analog circuit to improve performance and provide benefits, such as reducing the electromagnetic interference
(EMI) susceptibility.
Operational amplifiers vary in their susceptibility to radio frequency interference (RFI). RFI can generally be
identified as a variation in offset voltage or dc signal levels with changes in the interfering RF signal. The
OPA333A has been specifically designed to minimize susceptibility to RFI and demonstrates remarkably low
sensitivity compared to previous-generation devices. Strong RF fields may still cause varying offset levels.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
