The TLV313 family of single-, dual-, and quadchannel precision operational amplifiers combine low
power consumption with good performance. This
makes them suitable for a wide range of applications,
such as wearables, utility metering, building
automation, currency counters and more. The family
features rail-to-rail input and output (RRIO) swings,
low quiescent current (65 μA, typical), wide bandwidth
(1 MHz) and very low noise (26 nV/√Hz at 1 kHz),
making it attractive for a variety of battery-powered
applications that require a good balance between
cost and performance. Further, low-input-bias current
enables these devices to be used in applications with
megaohm source impedances.

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 pins are diode-clamped to the power-supply rails. Input signals that may swing more than 0.5 V beyond the supply rails must be
current limited to 10 mA or less.

8 Detailed Description
8.1 Overview
The TLVx313 family of operational amplifiers are general-purpose devices that are ideal for a wide range of
portable, low-cost applications. Rail-to-rail input and output swings, low quiescent current, and wide dynamic
range make the op amps well-suited for driving sampling analog-to-digital converters (ADCs) as well as other
single-supply applications.

SBOS753B – JUNE 2016 – REVISED FEBRUARY 2017
8.3 Feature Description
8.3.1 Operating Voltage
The TLV313 series is fully specified and tested from 1.8 V to 5.5 V (±0.9 V to ±2.75 V). Parameters that vary with
supply voltage are illustrated in the Typical Characteristics section.
8.3.2 Rail-to-Rail Input
The input common-mode voltage range of the TLV313 series extends 200 mV beyond the supply rails. This
performance is achieved with a complementary input stage: an N-channel input differential pair in parallel with a
P-channel differential pair, as shown in the Functional Block Diagram section. The N-channel pair is active for
input voltages close to the positive rail, typically (V+) – 1.3 V to 200 mV above the positive supply, while the Pchannel pair is on for inputs from 200 mV below the negative supply to approximately (V+) – 1.3 V. There is a
small transition region, typically (V+) – 1.4 V to (V+) – 1.2 V, in which both pairs are on. This 200-mV transition
region may vary up to 300 mV with process variation. Thus, the transition region (both stages on) may range
from (V+) – 1.7 V to (V+) – 1.5 V on the low end, up to (V+) – 1.1 V to (V+) – 0.9 V on the high end. Within this
transition region, PSRR, CMRR, offset voltage, offset drift, and THD may be degraded compared to device
operation outside this region.
8.3.3 Rail-to-Rail Output
Designed as a micro-power, low-noise operational amplifier, the TLV313 device 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 up to 100 kΩ, the output swings typically to within 5 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, as shown in Figure 12.
8.3.4 Common-Mode Rejection Ratio (CMRR)
CMRR for the TLV313 device is specified in several ways so the best match for a given application may be used;
see the Electrical Characteristics. First, the CMRR of the device in the common-mode range below the transition
region [VCM < (V+) – 1.3 V] is given. This specification is the best indicator of the capability of the device when
the application requires use of one of the differential input pairs. Second, the CMRR over the entire commonmode range is specified at (VCM = –0.2 V to 5.7 V). This last value includes the variations seen through the
transition region, as shown in Figure 4.
8.3.5 Capacitive Load and Stability
The TLV313 device is designed to be used in applications where driving a capacitive load is required. As with all
op amps, there may be specific instances where the TLV313 device may become unstable. The particular op
amp 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 op amp 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 op amp output resistance, creates a pole within the feedback
loop that degrades the phase margin. The degradation of the phase margin increases as the capacitive loading
increases. When operating in the unity-gain configuration, the TLV313 device remains stable with a pure
capacitive load up to approximately 1 nF. The equivalent series resistance (ESR) of some 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.

Feature Description (continued)
One technique for increasing the capacitive load drive capability of the amplifier when it operates 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 19.
This resistor significantly reduces the overshoot and ringing associated with large capacitive loads. One possible
problem with this technique 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 op amp, the dc offset observed at the amplifier output may shift from the nominal value
while EMI is present. This shift is a result of signal rectification associated with the internal semiconductor
junctions. While all op amp pin functions may be affected by EMI, the signal input pins are likely to be the most
susceptible. The TLV313 family incorporates an internal input low-pass filter that reduces the amplifiers response
to EMI. Both common-mode and differential mode filtering are provided by this filter. The filter is designed for a
cutoff frequency of approximately 35 MHz (–3 dB), with a roll-off of 20 dB per decade.
Texas Instruments has developed the ability to accurately measure and quantify the immunity of an operational
amplifier over a broad frequency spectrum extending from 10 MHz to 6 GHz. The EMI rejection ratio (EMIRR)
metric allows op amps to be directly compared by the EMI immunity. Figure 18 illustrates the results of this
testing on the TLV313 family. Detailed information may be found in EMI Rejection Ratio of Operational Amplifiers
(SBOA128), available for download from www.ti.com.
8.4 Device Functional Modes
The TLV313 devices have a single functional mode. The 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 TLVx313 devices are a family of low-power, rail-to-rail input and output operational amplifiers specifically
designed for portable applications. The 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 ≤ 10kΩ loads connected to any point between V+ and ground. The input common-mode voltage range includes both
rails, and allows the TLV313 family to be used in virtually any single-supply application.
9.2 Typical Application
A typical application for an operational amplifier is an inverting amplifier, as shown in Figure 20. An inverting
amplifier takes a positive voltage on the input and outputs a signal inverted to the input, making a negative
voltage of the same magnitude. In the same manner, the amplifier also makes negative input voltages positive on
the output. In addition, amplification may be added by selecting the input resistor RI and the feedback resistor RF.

9.2.1 Design Requirements
The supply voltage must be chosen to be larger than the input voltage range and the desired output range. The
limits of the input common-mode range (VCM) and the output voltage swing to the rails (VO) must also be
considered. For instance, this application scales a signal of ±0.5 V (1 V) to ±1.8 V (3.6 V). Setting the supply at
±2.5 V is sufficient to accommodate this application.

www.ti.com
Typical Application (continued)
When the desired gain is determined, choose a value for RI or RF. Choosing a value in the kilohm range is
desirable for general-purpose applications because the amplifier circuit uses currents in the milliamp range. This
milliamp current range ensures the device does not draw too much current. The trade-off is that very large
resistors (100s of kilohms) draw the smallest current but generate the highest noise. Small resistors (100s of
ohms) generate low noise but draw high current. This example uses 10 kΩ for RI, meaning 36 kΩ is used for RF.
The values are determined by Equation 3:

9.3 System Examples
When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required.
The simplest way to establish this limited bandwidth is to place an RC filter at the noninverting terminal of the
amplifier, as shown in Figure 22.

System Examples (continued)
If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter may be used for this
task, as shown in Figure 23. For best results, the amplifier must have a bandwidth that is eight to 10 times the
filter frequency bandwidth. Failure to follow this guideline may result in phase shift of the amplifier.

10 Power Supply Recommendations
The TLVx313 family 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. The Typical Characteristics section presents parameters that may 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, refer to the Layout
Guidelines section.
10.1 Input and ESD Protection
The TLV313 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case
of input and output pins, this protection primarily consists of current-steering diodes connected between the input
and power-supply pins. The ESD protection diodes also provide in-circuit, input overdrive protection, as long as
the current is limited to 10 mA as stated in the Absolute Maximum Ratings. Figure 24 shows how a series input
resistor may be added to the driven input to limit the input current. The added resistor contributes thermal noise
at the amplifier input and the 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 printed circuit board (PCB) layout practices, including:
• Noise may propagate into analog circuitry through the power pins of the circuit and the operational
amplifier. Use bypass capacitors to 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 usually 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, refer to 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 the 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. Keep RF and RG close to the inverting
input in order to minimize parasitic capacitance, as shown in Figure 25.
• 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 may significantly
reduce leakage currents from nearby traces that are at different potentials.
