•
•
•
•
•
•
The TLV674x family includes single (TLV6741), dual
(TLV6742), and quad-channel (TLV6744) generalpurpose CMOS operational amplifiers (op amp) that
provide a low noise figure of 3.5 nV/√Hz and a
wide bandwidth of 10 MHz. The low noise and
wide bandwidth make the TLV674x family of devices
attractive for a variety of precision applications
that require a good balance between cost and
performance. Additionally, the input bias current of the
TLV674x family supports applications with high source
impedance.
Low broadband noise: 3.5 nV/√Hz
Gain bandwidth: 10 MHz
Low input bias current: ±3 pA
Low offset voltage: 0.15 mV
Low offset voltage drift: ±0.2 µV/°C
Rail-to-rail output
Unity-gain stable
Low IQ:
– TLV6741: 890 µA/ch
– TLV6742/4: 990 µA/ch
Wide supply range:
– TLV6741: 2.25 V to 5.5 V
– TLV6742/4: 1.7 V to 5.5 V
Robust EMIRR performance: 71 dB at 2.4 GHz
•
•
The robust design of the TLV674x family provides
ease-of-use to the circuit designer due to its unity-gain
stability, integrated RFI/EMI rejection filter, no phase
reversal in overdrive conditions and high electrostatic
discharge (ESD) protection (2-kV HBM). Additionally,
the resistive open-loop output impedance makes them
easy to stabilize with much higher capacitive loads.

operation as low as 2.25 V (±1.125 V) for the
TLV6741 and 1.7 V (±0.85 V) for the TLV6742 and
TLV6744. All of the devices operate up to 5.5 V (±2.75
V), and are specified over the temperature range of
–40°C to 125°C.
The single-channel TLV6741 is available in a smallsize SC70-5 package. The dual-channel TLV6742 is
available in multiple package options including a tiny

Operating the device beyond the ratings listed under Absolute Maximum Ratings will cause permanent damage to the device.
These are stress ratings only, based on process and design limitations, and this device has not been designed to function outside
the conditions indicated under Recommended Operating Conditions. Exposure to any condition outside Recommended Operating
Conditions for extended periods, including absolute-maximum-rated conditions, may affect device reliability and performance.
Short-circuit to ground, one amplifier per package.
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.
Differential input voltages greater than 0.25 V applied continuously can result in a shift to the input offset voltage above the maximum
specification of this parameter. The magnitude of this effect increases as the ambient operating temperature rises.

8 Detailed Description
8.1 Overview
The TLV674x family is an ultra low-noise, rail-to-rail output operational amplifier family. These devices operate
from a supply voltage of 2.25 V to 5.5 V (TLV6741) and 1.7 V to 5.5 V (TLV6742 and TLV6744), are unity-gain
stable, and suitable for a wide range of general-purpose applications. The input common-mode voltage range
includes the negative rail and allows the TLV674x op amp family to be used in most single-supply applications.
Rail-to-rail output swing significantly increases dynamic range, especially in low-supply applications, and makes
it suitable for many audio applications as well as driving sampling analog-to-digital converters (ADCs).

8.3 Feature Description
8.3.1 THD+ Noise Performance
TLV674x operational amplifier family has excellent distortion characteristics. TLV6742 and TLV6744 THD +
Noise is below 0.00015% (G = +1, VO = 1 VRMS, VCM = 1.8 V, VS = 5.5 V) throughout the audio frequency range,
20 Hz to 20 kHz with a 10-kΩ load. TLV6741 THD + Noise is below 0.00035% (G = +1, VO = 1 VRMS, V CM = 2.5
V, VS = 5.5 V) throughout the audio frequency range, 20 Hz to 20 kHz, with a 10-kΩ load. Broadband noise of
3.5 nV/√ Hz (TLV6742/4) and 3.7 nV/√ Hz (TLV6741) is extremely low for a 10-MHz general purpose amplifier.
8.3.2 Operating Voltage
The TLV674x operational amplifier family is fully specified and assured for operation from 1.7 V to 5.5 V
(TLV6742/4) and 2.25 V to 5.5 V (TLV6741). In addition, many specifications apply from –40°C to 125°C.
Power-supply pins should be bypassed with 0.1-µF ceramic capacitors.
8.3.3 Rail-to-Rail Output
Designed as a low-power, low-voltage operational amplifier, the TLV674x devices deliver a robust output
drive capability. A class AB output stage with common-source transistors achieves full rail-to-rail output swing
capability. For resistive loads of 10-kΩ, the output swings to within a few mV of either supply rail, regardless of
the applied power-supply voltage. Different load conditions change the ability of the amplifier to swing close to
the rails, see Figure 7-11.

8.3.4 EMI Rejection
The TLV674x uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from
sources such as wireless communications and densely-populated boards with a mix of analog signal chain and
digital components. EMI immunity can be improved with circuit design techniques; the TLV674x benefits from
these design improvements. 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. Figure
8-1 shows the results of this testing on the TLV674x. Table 8-1 shows the EMIRR IN+ values for the TLV674x at
particular frequencies commonly encountered in real-world applications. The EMI Rejection Ratio of Operational
Amplifiers application report contains detailed information on the topic of EMIRR performance as it relates to op
amps and is available for download from www.ti.com.

8.3.5 Electrical Overstress
Designers often ask questions about the capability of an operational amplifier to withstand electrical overstress
(EOS). These questions tend to focus on the device inputs, but may involve the supply voltage pins or even
the output pin. Each of these different pin functions have electrical stress limits determined by the voltage
breakdown characteristics of the particular semiconductor fabrication process and specific circuits connected to
the pin. Additionally, internal electrostatic discharge (ESD) protection is built into these circuits to protect them
from accidental ESD events both before and during product assembly.
Having a good understanding of this basic ESD circuitry and its relevance to an electrical overstress event is
helpful. Figure 8-2 shows an illustration of the ESD circuits contained in the TLV674x (indicated by the dashed
line area). The ESD protection circuitry involves several current-steering diodes connected from the input and
output pins and routed back to the internal power-supply lines, where the diodes meet at an absorption device
or the power-supply ESD cell, internal to the operational amplifier. This protection circuitry is intended to remain
inactive during normal circuit operation.

Figure 8-2. Equivalent Internal ESD Circuitry Relative to a Typical Circuit Application
An ESD event is very short in duration and very high voltage (for example; 1 kV, 100 ns), whereas an EOS
event is long in duration and lower voltage (for example; 50 V, 100 ms). The ESD diodes are designed for
out-of-circuit ESD protection (that is, during assembly, test, and storage of the device before being soldered to
the PCB). During an ESD event, the ESD signal is passed through the ESD steering diodes to an absorption
circuit (labeled ESD power-supply circuit). The ESD absorption circuit clamps the supplies to a safe level.
Although this behavior is necessary for out-of-circuit protection, excessive current and damage is caused if
activated in-circuit. A transient voltage suppressor (TVS) can be used to prevent against damage caused by
turning on the ESD absorption circuit during an in-circuit ESD event. Using the appropriate current limiting
resistors and TVS diodes allows for the use of device ESD diodes to protect against EOS events.

The TLV674x family incorporates internal electrostatic discharge (ESD) protection circuits on all pins, as shown
above. These ESD protection diodes also provide in-circuit, input overdrive protection, as long as the current is
limited to 10 mA as stated in Section 7.1. Figure 8-3 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 its
value should be kept to a minimum in noise-sensitive applications.

8.3.6 Typical Specifications and Distributions
Designers often have questions about a typical specification of an amplifier in order to design a more robust
circuit. Due to natural variation in process technology and manufacturing procedures, every specification of an
amplifier will exhibit some amount of deviation from the ideal value, like an amplifier's input offset voltage. These
deviations often follow Gaussian ("bell curve"), or normal, distributions and circuit designers can leverage this
information to guardband their system, even when there is not a minimum or maximum specification in Section
7.6.

Figure 8-4. Ideal Gaussian Distribution
Figure 8-4 shows an example distribution, where µ, or mu, is the mean of the distribution, and where σ,
or sigma, is the standard deviation of a system. For a specification that exhibits this kind of distribution,
approximately two-thirds (68.26%) of all units can be expected to have a value within one standard deviation, or
one sigma, of the mean (from µ–σ to µ+σ).
Depending on the specification, values listed in the typical column of Section 7.6 are represented in different
ways. As a general rule of thumb, if a specification naturally has a nonzero mean (for example, like gain
bandwidth), then the typical value is equal to the mean (µ). However, if a specification naturally has a mean near

zero (like input offset voltage), then the typical value is equal to the mean plus one standard deviation (µ + σ) in
order to most accurately represent the typical value.
You can use this chart to calculate approximate probability of a specification in a unit; for example, for TLV6742,
the typical input voltage offset is 150 µV, so 68.2% of all TLV6742 devices are expected to have an offset from
–150 µV to 150 µV.
Specifications with a value in the minimum or maximum column are assured by TI, and units outside these limits
will be removed from production material. For example, the TLV6742 device has a maximum offset voltage of
1.0 mV at 25°C, and even though this corresponds to 5 σ (≈1 in 1.7 million units), which is extremely unlikely, TI
assures that any unit with a larger offset than 1.0 mV will be removed from production material.
For specifications with no value in the minimum or maximum column, consider selecting a sigma value of
sufficient guardband for your application, and design worst-case conditions using this value. For example, the
6σ value corresponds to about 1 in 500 million units, which is an extremely unlikely chance, and could be an
option as a wide guardband to design a system around. In this case, the TLV6742 does not have a maximum or
minimum for offset voltage drift, but based on Figure 7-40 and the typical value of 0.2 µV/°C in Section 7.6, it can
be calculated that the 6-σ value for offset voltage drift is about 1.0 µV/°C. When designing for worst-case system
conditions, this value can be used to estimate the worst possible offset across temperature without having an
actual minimum or maximum value.
However, process variation and adjustments over time can shift typical means and standard deviations, and
unless there is a value in the minimum or maximum specification column, TI cannot assure the performance of a
device. This information should be used only to estimate the performance of a device.
8.3.7 Shutdown Function
The TLV674xS devices feature SHDN pins that disable the op amp, placing it into a low-power standby mode.
In this mode, the op amp typically consumes less than 1 µA. The SHDN pins are active-low, meaning that
shutdown mode is enabled when the input to the SHDN pin is a valid logic low.
The SHDN pins are referenced to the negative supply voltage of the op amp. The threshold of the shutdown
feature lies around 800 mV (typical) above the negative rail. Hysteresis has been included in the switching
threshold to ensure smooth switching characteristics. To ensure optimal shutdown behavior, the SHDN pins
should be driven with valid logic signals. A valid logic low is defined as a voltage between V– and V– + 0.2 V. A
valid logic high is defined as a voltage between V– + 1.2 V and V+. The shutdown pin must either be connected
to a valid high or a low voltage or driven, and not left as an open circuit. There is no internal pull-up to enable the
amplifier.
The SHDN pins are high-impedance CMOS inputs. Dual op amp versions are independently controlled, and
quad op amp versions are controlled in pairs with logic inputs. For battery-operated applications, this feature
may be used to greatly reduce the average current and extend battery life. The enable time is 15 µs for full
shutdown of all channels; disable time is 3 µs. When disabled, the output assumes a high-impedance state. This
architecture allows the TLV674xS to be operated as a gated amplifier (or to have the device output multiplexed
onto a common analog output bus). Shutdown time (tOFF) depends on loading conditions and increases as load
resistance increases. To ensure shutdown (disable) within a specific shutdown time, the specified 10-kΩ load
to midsupply (VS / 2) is required. If using the TLV674xS without a load, the resulting turnoff time is significantly
increased.
8.3.8 Packages With an Exposed Thermal Pad
The TLV674x family is available in packages such as the WSON-8 (DSG) which feature an exposed thermal
pad. Inside the package, the die is attached to this thermal pad using an electrically conductive compound. For
this reason, when using a package with an exposed thermal pad, the thermal pad must either be connected to
V– or left floating. Attaching the thermal pad to a potential other than V– is not allowed, and performance of the
device is not assured when doing so.

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 TLV674x family features 10-MHz bandwidth and 4.5-V/µs slew rate with only 890-µA (TLV6741), 990-µA
(TLV6742/4) of 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 3.5 nV /vHz (TLV6742/4), 3.7 nV / vHz
(TLV6741) at 10 kHz, low input bias current, and a typical input offset voltage of 0.15 mV.
9.2 Single-Supply Electret Microphone Preamplifier With Speech Filter
Electret microphones are commonly used in portable electronics because of their small size, low cost, and
relatively good signal-to-noise ratio (SNR). The small package size, low operating voltage and excellent AC
performance of the TLV674x family make it an excellent choice for preamplifier circuits for electret microphones.
The circuit shown in Figure 9-1 is a single-supply preamplifier circuit for electret microphones, highlighting the
TLV6741 device.

10 Power Supply Recommendations
The TLV6742 and TLV6744 devices are specified for operation from 1.7 V to 5.5 V (±0.85 V to ±2.75 V). The
TLV6741 device is specified for operation from 2.25 V to 5.5 V (±1.125 V to ±2.75 V). Many specifications of the
TLV674x family apply from –40°C to 125°C.
CAUTION
Supply voltages larger than 7 V can permanently damage the device (see Section 7.1).
Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or
high-impedance power supplies. For more detailed information on bypass capacitor placement, see Section
11.1.

11 Layout
11.1 Layout Guidelines
For best operational performance of the device, use good PCB layout practices, including:
•
•
•
•
•
•
36
Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational
amplifier. Bypass capacitors are used 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. Make sure to physically separate digital
and analog grounds, paying attention to the flow of the ground current.
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 Figure 11-1.
Keep the length of input traces as short as possible. Always 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.
