SBOS752A – FEBRUARY 2016 – REVISED SEPTEMBER 2016
TLVx316
10-MHz, Rail-to-Rail Input/Output, Low-Voltage, 1.8-V CMOS Operational Amplifiers
1 Features
3 Description
•
•
The TLV316 (single), TLV2316 (dual), and TLV4316
(quad) devices comprise a family of general-purpose,
low-power operational amplifiers. Features such as
rail-to-rail input and output swings, low quiescent
current (400 μA/ch typical) combined with a wide
bandwidth of 10 MHz, and very-low noise (12 nV/√Hz
at 1 kHz) make this family attractive for a variety of
applications that require a good balance between
cost and performance. The low input bias current
supports operational amplifiers that are used in
applications with megaohm source impedances.

The robust design of the TLVx316 provides ease-ofuse to the circuit designer—a unity-gain stable,
integrated RFI/EMI rejection filter, no phase reversal
in overdrive condition, and high electrostatic
discharge (ESD) protection (4-kV HBM).
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). This latest addition of low-voltage CMOS
operational amplifiers to the portfolio, in conjunction
with the TLVx313 and TLVx314 series, offer a family
of bandwidth, noise, and power options to meet the
needs of a wide variety of applications.

8 Detailed Description
8.1 Overview
The TLVx316 is a family of low-power, rail-to-rail input and output operational amplifiers. These devices operate
from 1.8 V to 5.5 V, are unity-gain stable, and are suitable for a wide range of general-purpose applications. The
class AB output stage is capable of driving ≤ 10-kΩ loads connected to any point between V+ and ground. The
input common-mode voltage range includes both rails and allows the TLVx316 to be used in virtually any singlesupply application. Rail-to-rail input and output swing significantly increases dynamic range, especially in lowsupply applications, and makes them suitable for driving sampling analog-to-digital converters (ADCs).
The TLVx316 features 10-MHz bandwidth and 6-V/μs slew rate with only 400-μA supply current per channel,
providing good ac performance at very-low power consumption. DC applications are well served with a very-low
input noise voltage of 12 nV/√Hz at 1 kHz, low input bias current (5 pA), and an input offset voltage of 0.5 mV
(typical).

8.3 Feature Description
8.3.1 Operating Voltage
The TLVx316 operational amplifiers are fully specified and ensured for operation from 1.8 V to 5.5 V. In addition,
many specifications apply from –40°C to +125°C. Parameters that vary significantly with operating voltages or
temperature are illustrated in the Typical Characteristics section.
8.3.2 Rail-to-Rail Input
The input common-mode voltage range of the TLVx316 extends 200 mV beyond the supply rails for supply
voltages greater than 2.5 V. This performance is achieved with a complementary input stage: an N-channel input
differential pair in parallel with a P-channel differential pair; see the Functional Block Diagram section. The Nchannel pair is active for input voltages close to the positive rail, typically (V+) – 1.4 V to 200 mV above the
positive supply, whereas the P-channel pair is active for inputs from 200 mV below the negative supply to
approximately (V+) – 1.4 V. There is a small transition region, typically (V+) – 1.2 V to (V+) – 1 V, in which both
pairs are on. This 200-mV transition region can vary up to 200 mV with process variation. Thus, the transition
region (both stages on) can range from (V+) – 1.4 V to (V+) – 1.2 V on the low end, up to (V+) – 1 V to (V+) –
0.8 V on the high end. Within this transition region, PSRR, CMRR, offset voltage, offset drift, and THD can be
degraded compared to device operation outside this region.
8.3.3 Rail-to-Rail Output
Designed as a low-power, low-voltage operational amplifier, the TLVx316 delivers a robust output drive
capability. A class AB output stage with common-source transistors is used to achieve full rail-to-rail output swing
capability. For resistive loads of 10 kΩ, the output swings typically to within 30 mV of either supply rail regardless
of the power-supply voltage applied. Different load conditions change the ability of the amplifier to swing close to
the rails; see typical characteristic graph Output Voltage Swing vs Output Current ().
8.3.4 Common-Mode Rejection Ratio (CMRR)
CMRR for the TLVx316 is specified in two ways so the best match for a given application can be selected. First,
the Electrical Characteristics table provides the CMRR of the device in the common-mode range below the
transition region [VCM < (V+) – 1.4 V]. This specification is the best indicator of device capability when the
application requires using one of the differential input pairs. Second, the CMRR over the entire common-mode
range is specified at VCM = –0.2 V to 5.7 V for VS = 5.5 V. This last value includes the variations through the
transition region.
8.3.5 Capacitive Load and Stability
The TLVx316 is designed to be used in applications where driving a capacitive load is required. As with all
operational amplifiers, there may be specific instances where the TLVx316 can become unstable. The particular
operational amplifier circuit configuration, layout, gain, and output loading are some of the factors to consider
when establishing whether or not an amplifier is stable in operation. An operational amplifier in the unity-gain
(1 V/V) buffer configuration that drives a capacitive load exhibits a greater tendency to be unstable than an
amplifier operated at a higher noise gain. The capacitive load, in conjunction with the operational amplifier output
resistance, creates a pole within the feedback loop that degrades the phase margin. The degradation of the
phase margin increases when the capacitive loading increases. For a conservative best practice, designing for
25% overshoot (40° phase margin) provides improved stability over process variations. The equivalent series
resistance (ESR) of some very-large capacitors (CL greater than 1 μF) is sufficient to alter the phase
characteristics in the feedback loop such that the amplifier remains stable. Increasing the amplifier closed-loop
gain allows the amplifier to drive increasingly larger capacitance. This increased capability is evident when
observing the overshoot response of the amplifier at higher voltage gains. See typical characteristic graph,
Small-Signal Overshoot vs Capacitive Load (Figure 7, G = –1 V/V).

Feature Description (continued)
One technique for increasing the capacitive load drive capability of the amplifier operating in a unity-gain
configuration is to insert a small resistor (typically 10 Ω to 20 Ω) in series with the output, as shown in Figure 14.
This resistor significantly reduces the overshoot and ringing associated with large capacitive loads. One possible
problem with this technique, however, is that a voltage divider is created with the added series resistor and any
resistor connected in parallel with the capacitive load. The voltage divider introduces a gain error at the output
that reduces the output swing.

8.3.6 EMI Susceptibility and Input Filtering
Operational amplifiers vary with regard to the susceptibility of the device to electromagnetic interference (EMI). If
conducted EMI enters the operational amplifier, the dc offset measured at the amplifier output can shift from its
nominal value when EMI is present. This shift is a result of signal rectification associated with the internal
semiconductor junctions. Although all operational amplifier pin functions can be affected by EMI, the signal input
pins are likely to be the most susceptible. The TLVx316 operational amplifier family incorporates an internal input
low-pass filter that reduces the amplifier response to EMI. This filter provides both common-mode and
differential-mode filtering. The filter is designed for a cutoff frequency of approximately 80 MHz (–3 dB), with a
roll-off of 20 dB per decade.
The immunity of an operational amplifier can be accurately measured and quantified over a broad frequency
spectrum extending from 10 MHz to 6 GHz. The EMI rejection ratio (EMIRR) metric allows operational amplifiers
to be directly compared by the EMI immunity. Figure 12 illustrates the results of this testing on the TLVx316.
Detailed information can be found in EMI Rejection Ratio of Operational Amplifiers (SBOA128), available for
download from www.ti.com.
8.3.7 Overload Recovery
Overload recovery is defined as the time required for the operational amplifier output to recover from a saturated
state to a linear state. The output devices of the operational amplifier enter a saturation region when the output
voltage exceeds the rated operating voltage, either because of the high input voltage or the high gain. After the
device enters the saturation region, the charge carriers in the output devices require time to return back to the
linear state. After the charge carriers return back to the linear state, the device begins to slew at the specified
slew rate. Thus, the propagation delay in case of an overload condition is the sum of the overload recovery time
and the slew time. The overload recovery time for the TLVx316 is approximately 300 ns.
8.4 Device Functional Modes
The TLVx316 have a single functional mode. These devices are powered on as long as the power-supply voltage
is between 1.8 V (±0.9 V) and 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 TLV316, TLV2316, and TLV4316 are powered on when the supply is connected. The devices can be
operated as a single-supply operational amplifier or a dual-supply amplifier, depending on the application.
9.2 System Examples
When receiving low-level signals, the device often requires limiting the bandwidth of the incoming signals into the
system. The simplest way to establish this limited bandwidth is to place an RC filter at the noninverting pin of the
amplifier, as shown in Figure 15.

If even more attenuation is needed, the device requires a multiple-pole filter. The Sallen-Key filter can be used
for this task, as shown in Figure 16. For best results, the amplifier must have a bandwidth that is eight to ten
times the filter frequency bandwidth. Failure to follow this guideline can result in a phase shift of the amplifier.

10 Power Supply Recommendations
The TLVx316 is specified for operation from 1.8 V to 5.5 V (±0.9 V to ±2.75 V); many specifications apply from
–40°C to +125°C. Typical Characteristics presents parameters that can exhibit significant variance with regard to
operating voltage or temperature.
CAUTION
Supply voltages larger than 7 V can permanently damage the device (see the Absolute
Maximum Ratings table).
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or highimpedance power supplies. For more detailed information on bypass capacitor placement, see Layout
Guidelines.
10.1 Input and ESD Protection
The TLVx316 incorporates internal ESD protection circuits on all pins. For input and output pins, this protection
primarily consists of current-steering diodes connected between the input and power-supply pins. These ESD
protection diodes provide in-circuit, input overdrive protection, as long as the current is limited to 10 mA, as
stated in the Absolute Maximum Ratings table. Figure 17 shows how a series input resistor can be added to the
driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input and its
value must be kept to a minimum in noise-sensitive applications.

11 Layout
11.1 Layout Guidelines
For best operational performance of the device, use good PCB layout practices, including:
• Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the
operational amplifier. Bypass capacitors reduce the coupled noise by providing low-impedance power
sources local to the analog circuitry.
– Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as
close to the device as possible. A single bypass capacitor from V+ to ground is applicable for singlesupply applications.
• Separate grounding for analog and digital portions of the circuitry is one of the simplest and most
effective methods of noise suppression. One or more layers on multilayer PCBs are typically devoted to
ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Take care to
physically separate digital and analog grounds, paying attention to the flow of the ground current. For
more detailed information, see , Circuit Board Layout Techniques (SLOA089).
• To reduce parasitic coupling, run the input traces as far away from the supply or output traces as
possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicularly is much
better than crossing in parallel with the noisy trace.
• Place the external components as close to the device as possible. Keeping RF and RG close to the
inverting input minimizes parasitic capacitance, as shown in Layout Example.
• Keep the length of input traces as short as possible. Remember that the input traces are the most
sensitive part of the circuit.
• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly
reduce leakage currents from nearby traces that are at different potentials.
