Product details
Overview
TLV2774AIDG4 from Texas Instruments is a quad CMOS operational amplifier with rail-to-rail output, 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, and 1 mA per-channel supply current, operating from 2.5 V to 5.5 V. It delivers low distortion (0.005% THD+N into 600 Ω) and 360 µV input offset voltage, making it suitable for precision signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2774AIDG4 datasheet, TLV2774AIDG4 pinout, TLV2774AIDG4 application, or TLV2774AIDG4 equivalent, key selection criteria include its −40°C to 125°C temperature rating, micropower shutdown mode (<1 µA), 17 nV/√Hz input noise, and compatibility with single-supply ADC driver topologies requiring high output drive and dc precision.
Technical Context
The TLV2774AIDG4 implements a CMOS input stage with rail-to-rail output swing, enabling full dynamic range utilization in low-voltage systems. Its 5.1 MHz bandwidth and 10.5 V/µs slew rate support fast settling for multiplexed analog front-ends, while the 2 pA input bias current minimizes error in high-impedance sensor node applications.
It features micropower shutdown control (1/2SHDN and 3/4SHDN pins), allowing independent channel disablement to reduce system-level quiescent current. The device is characterized across extended temperature ranges and meets automotive Q-Temp qualification requirements for reliability-critical environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774CDR | Same architecture but C-temp grade (0°C to 70°C); 2.7 mV max VIO vs. 2.1 mV for TLV2774AIDG4 | Limited to commercial ambient environments; not qualified for automotive or industrial enclosures | Select when cost sensitivity outweighs extended temperature or automotive qualification needs |
| OPA2333AIDR | Zero-drift topology; 0.02 µV/°C offset drift vs. 2 µV/°C for TLV2774AIDG4; higher 350 nA IB | Better long-term dc stability in unattended monitoring; higher power (17 µA/ch) limits battery life | Select when ultra-low drift dominates over power and speed requirements |
Compared with TLV2774CDR, TLV2774AIDG4 provides tighter offset (2.1 mV vs. 2.7 mV), extended temperature range, and automotive qualification-critical for under-hood or factory-floor deployment. Versus OPA2333AIDR, TLV2774AIDG4 offers 10× faster slew rate and 60× lower supply current, trading zero-drift precision for speed and efficiency.

FAQ
What is the maximum operating temperature range for TLV2774AIDG4?
The TLV2774AIDG4 is rated for operation from −40°C to 125°C, meeting automotive Q-Temp specifications. This extended range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and gain-bandwidth product, ensuring reliable performance in under-hood or industrial control cabinet environments where ambient temperatures exceed 85°C.
Does TLV2774AIDG4 support rail-to-rail input operation?
No, TLV2774AIDG4 features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 2.0 V at 3.3 V supply), meaning the inputs cannot accept signals within 1.3 V of the positive rail. This limitation requires careful biasing in single-supply applications where input signals approach VDD.
How does the shutdown functionality work on TLV2774AIDG4?
The TLV2774AIDG4 uses dual independent shutdown pins: Pins 8 (1/2SHDN) and 12 (3/4SHDN). Driving either pin low disables the corresponding pair of amplifiers (Channels 1&2 or 3&4), reducing their supply current to <1 µA per channel. Both pins must be high for full four-channel operation. No external pull-up resistors are required-the internal logic interprets TTL/CMOS-compatible levels directly.
Can TLV2774AIDG4 drive a 600-Ω load with low distortion?
Yes, TLV2774AIDG4 is specifically characterized for 600-Ω loading: at 1 kHz, it achieves 0.005% THD+N with AV = 1, and 0.016% at AV = 10 (VDD = 5 V). Its 10.5 V/µs slew rate and rail-to-rail output ensure clean signal reproduction into legacy telecom and audio line impedances without clipping or harmonic generation.
What package type is used for TLV2774AIDG4?
TLV2774AIDG4 is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package designated as 'D' by Texas Instruments. It measures 8.65 mm × 3.91 mm with 1.27 mm lead pitch and includes an exposed thermal pad for enhanced heat dissipation-critical for maintaining parametric stability during sustained 1 mA/channel operation at elevated ambient temperatures.
