Product details
Overview
TLV2774AIPW from Texas Instruments is a quad CMOS rail-to-rail output operational amplifier optimized for precision, low-power, single-supply systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max), 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity signal conditioning in automotive sensor front-ends and portable data acquisition.
For engineers reviewing the TLV2774AIPW datasheet, TLV2774AIPW pinout, TLV2774AIPW application, or TLV2774AIPW equivalent, this device supports critical design decisions involving rail-to-rail output swing into 600-Ω loads, micropower shutdown (<1 µA/channel), −40°C to 125°C operation, and low THD+N (0.005% at 1 kHz) for analog-to-digital converter driving and telecom line interface stages.
Technical Context
The TLV2774AIPW employs a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage at 10 kHz, enabling high-impedance sensor interfacing without significant error contribution. Its rail-to-rail output stage delivers full-swing capability across the entire supply range, supporting accurate reference buffering and ADC input scaling.
It features integrated micropower shutdown control (1/2SHDN and 3/4SHDN pins), allowing independent channel disablement to reduce system-level quiescent current. The device is characterized over extended temperature (−40°C to 125°C) and qualified to automotive standards, confirming robustness in engine control and ADAS signal chains.
Key Specifications

Pinout & Package
TSSOP-14 package (PW suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, thermally enhanced pad (exposed die attach pad not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives external load or next-stage input with rail-to-rail swing. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback network or differential sensing node. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts sensor, reference, or signal source with high-impedance interface. |
| 4 | VDD | Positive supply rail - must be decoupled locally (0.1 µF ceramic + 1–10 µF bulk) for stability. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - isolated from Channel 1 for dual-path signal processing. |
| 6 | 2IN− | Inverting input of Channel 2 - supports independent gain configuration per channel. |
| 7 | 2OUT | Output of Channel 2 - electrically isolated; shares no internal nodes with Channel 1. |
| 8 | 1/2SHDN | Shutdown control for Channels 1 & 2 - logic-high disables both outputs and reduces IDD to <1 µA. |
| 9 | 4OUT | Output of Channel 4 - fully independent output stage with same drive capability as Channel 1. |
| 10 | 4IN− | Inverting input of Channel 4 - supports high-precision differential measurement topologies. |
| 11 | 4IN+ | Non-inverting input of Channel 4 - compatible with low-noise, high-Z sources (e.g., thermocouples). |
| 12 | GND | Analog ground reference - must be tied to system AGND plane with low-inductance connection. |
| 13 | 3IN+ | Non-inverting input of Channel 3 - enables simultaneous multi-channel signal conditioning on one IC. |
| 14 | 3/4SHDN | Shutdown control for Channels 3 & 4 - independent of Pin 8, enabling asymmetric power management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IPW | Same architecture and pinout, but rated for −40°C to 125°C (I-suffix) instead of A-suffix's tighter 1.6 mV VIO max spec. | Lower-cost option where input offset voltage ≤2.7 mV is acceptable; not qualified for automotive AEC-Q100. | Select TLV2774IPW for industrial temperature-range designs where cost sensitivity outweighs ultra-low offset requirement. |
| OPA4340UA | Higher 5.5 MHz GBW, lower 12 nV/√Hz noise, but higher 750 µA/channel supply current and no shutdown pins. | Better for wideband, low-noise applications (e.g., medical ECG front-end); lacks independent channel shutdown for power gating. | Choose OPA4340UA when bandwidth and noise dominate over power budget and channel-level control. |
Compared with TLV2774IPW, the TLV2774AIPW offers guaranteed lower input offset (1.6 mV vs. 2.7 mV) and automotive qualification, while OPA4340UA trades shutdown capability and micropower operation for superior AC performance and noise floor.

FAQ
What is the maximum supply voltage rating for TLV2774AIPW?
The absolute maximum supply voltage for TLV2774AIPW is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks exceeding safe dissipation limits and may degrade long-term reliability, especially at elevated temperatures. Always observe derating curves in the datasheet for TSSOP-14 package power handling.
Does TLV2774AIPW support true rail-to-rail input?
No, TLV2774AIPW features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at 2.7 V supply), meaning it cannot accept signals within 1.3 V of VDD. For full rail-to-rail input capability, consider TI's TLV2464 or OPA4340 - neither of which match TLV2774AIPW's micropower shutdown or automotive qualification.
How does the shutdown functionality work on TLV2774AIPW?
TLV2774AIPW has two independent shutdown controls: Pin 8 (1/2SHDN) disables Channels 1 and 2, while Pin 14 (3/4SHDN) disables Channels 3 and 4. A logic-high input (≥2.0 V) places the respective pair into micropower state with IDD < 1 µA per channel. Both pins must be pulled high to fully shut down all four channels.
Is TLV2774AIPW qualified for automotive applications?
Yes, TLV2774AIPW carries the "A" temperature grade (−40°C to 125°C) and is explicitly listed in TI's Q-Temp Automotive documentation. It meets AEC-Q100 stress testing requirements for automotive use, including qualification for engine control, body electronics, and ADAS sensor signal chains - unlike the standard "I" or "C" variants.
What is the typical input bias current of TLV2774AIPW at 25°C?
The typical input bias current of TLV2774AIPW is 2 pA at 25°C, with a maximum of 350 pA over the full −40°C to 125°C range. This ultra-low value enables high-impedance sensor interfacing (e.g., pH electrodes, piezoelectric transducers) without significant offset drift due to leakage across feedback networks.
