Product details
Overview
TLV2774AIPWR from Texas Instruments is a quad CMOS operational amplifier with rail-to-rail output, 5.1 MHz gain-bandwidth product, 10.5 V/µs slew rate, and 1 mA per-channel supply current at 5 V. It operates from 2.5 V to 5.5 V single supply and is characterized across −40°C to 125°C for automotive sensor signal conditioning and precision analog front-ends.
For engineers reviewing the TLV2774AIPWR datasheet, TLV2774AIPWR pinout, TLV2774AIPWR application, or TLV2774AIPWR equivalent, key selection criteria include its 360 µV max input offset voltage (A-grade), micropower shutdown mode (<1 µA/channel), low THD+N (0.005% into 600 Ω), and TSSOP-14 package compatibility with space-constrained industrial data acquisition systems.
Technical Context
The TLV2774AIPWR uses a CMOS input stage delivering 2 pA typical input bias current and 17 nV/√Hz input noise voltage at 10 kHz. Its rail-to-rail output stage supports full-swing operation into 600-Ω loads while maintaining 0.005% THD+N - critical for driving SAR ADC reference inputs and telecom line drivers.
It features independent shutdown control for channels 1/2 and 3/4 (pins 6 and 13), enabling dynamic power management in multi-stage analog signal chains. The device achieves 46° phase margin and 12 dB gain margin with 600-Ω load and 100-pF capacitive load, ensuring stable unity-gain operation without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IPWR | Standard grade (I-suffix): 2.7 mV max input offset vs. 2.1 mV for A-grade; same pinout, package, and electrical specs otherwise | Valid for commercial/industrial use where ±0.1% sensor accuracy suffices; not qualified for automotive AEC-Q100 | Select TLV2774IPWR for cost-sensitive non-automotive designs requiring identical footprint and functionality |
| OPA4376AIPWR | Lower input offset (12 µV typ), lower noise (4.6 nV/√Hz), but higher supply current (760 µA/channel) and no shutdown pins | Better for ultra-precision DC-coupled systems (e.g., weigh scales); unsuitable where dynamic power gating is required | Choose OPA4376AIPWR only when sub-100-µV offset and <5 nV/√Hz noise outweigh shutdown capability and 4× higher quiescent power |
Compared with TLV2774IPWR, the TLV2774AIPWR offers tighter input offset and automotive qualification; versus OPA4376AIPWR, it trades precision for micropower shutdown and lower cost - making it optimal for battery-powered automotive and industrial sensor nodes.

FAQ
What is the maximum operating temperature range for the TLV2774AIPWR?
The TLV2774AIPWR is specified for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. This rating is validated across all electrical parameters including input offset voltage, CMRR, and supply current - unlike commercial-grade variants limited to 0°C–70°C.
Does the TLV2774AIPWR support true rail-to-rail input?
No, the TLV2774AIPWR features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), excluding the positive rail. For true rail-to-rail input capability, consider TI's TLV9064 or OPA4991 families - but those lack the TLV2774AIPWR's micropower shutdown and AEC-Q100 qualification.
How does the shutdown function work on the TLV2774AIPWR?
The TLV2774AIPWR has two independent shutdown pins: Pin 8 (1/2SHDN) disables Channels 1 and 2, while Pin 13 (3/4SHDN) disables Channels 3 and 4. Both are active-low; pulling either pin below 0.8 V (at VDD = 5 V) reduces respective channel supply current to <1.5 µA. Outputs enter high-impedance state, and recovery time is 2.4 µs (Ch1/2) or 1.9 µs (Ch3/4) to 50% of final value.
Can the TLV2774AIPWR drive a 600-Ω load with low distortion?
Yes - the TLV2774AIPWR delivers 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, as verified in the official datasheet (SLOS209G, page 9). This performance is enabled by its high slew rate (10.5 V/µs) and optimized output stage, making it suitable for telecom line drivers and audio preamplifiers where spectral purity is critical.
What is the input bias current specification for the TLV2774AIPWR?
The TLV2774AIPWR has a typical input bias current of 2 pA and a maximum of 350 pA over the full −40°C to +125°C temperature range (per datasheet SLOS209G, page 12). This ultra-low bias current minimizes voltage errors in high-impedance sensor interfaces such as pH electrodes, photodiode transimpedance stages, and piezoelectric signal conditioning circuits.
