Product details
Overview
TLV2774AIDR from Texas Instruments is a quad CMOS rail-to-rail output operational amplifier optimized for single-supply, low-voltage portable and automotive applications. 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 ADC driver and sensor front-end circuits.
For engineers reviewing the TLV2774AIDR datasheet, TLV2774AIDR pinout, TLV2774AIDR application, or TLV2774AIDR equivalent, key selection criteria include its −40°C to 125°C extended temperature rating, micropower shutdown mode (<1 µA per channel), low THD+N (0.005% at 1 kHz into 600 Ω), and SOIC-14 package compatibility with space-constrained industrial and automotive PCB layouts.
Technical Context
The TLV2774AIDR uses a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage, supporting precision DC-coupled measurement paths. Its rail-to-rail output swing enables full dynamic range utilization with 2.5 V–5.5 V supplies, while the 5.1 MHz bandwidth and 10.5 V/µs slew rate support fast-settling, wideband analog signal chains.
It integrates independent shutdown control for channels 1/2 and 3/4 (pins 7 and 14), allowing selective power gating without external logic. The device is characterized across −40°C to 125°C and qualified to AEC-Q100 for automotive use, with input common-mode range extending to within 1.3 V of VDD and GND.

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 |
|---|---|---|---|
| TLV2774IDR | Same electrical specs but rated for −40°C to 125°C (I-suffix) without AEC-Q100 validation; no automotive qualification documentation | Acceptable for industrial temperature-grade designs where automotive reliability testing is not mandated | Select TLV2774IDR only if AEC-Q100 compliance is unnecessary and cost sensitivity outweighs long-term automotive lifecycle assurance |
| OPA2377AIDR | Lower 3.5 MHz GBW, 2.5 V/µs slew rate, but superior 5.5 µV max VIO and 7 nV/√Hz noise; no shutdown function | Better suited for ultra-precision DC applications (e.g., weigh scales), not high-speed or power-gated systems | Choose OPA2377AIDR when offset and noise dominate requirements and shutdown capability is irrelevant |
Compared with TLV2774IDR, TLV2774AIDR adds documented AEC-Q100 Grade 2 qualification and tighter VIO distribution (1.6 mV max vs. 2.7 mV), making it mandatory for automotive safety-critical subsystems; versus OPA2377AIDR, it trades noise/offset performance for higher speed, lower power, and integrated shutdown - prioritizing versatility in mixed-signal automotive ECUs.

FAQ
What is the maximum supply voltage for TLV2774AIDR?
The absolute maximum supply voltage for TLV2774AIDR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks exceeding internal junction temperature limits and invalidates AEC-Q100 qualification. At 5.5 V, the device maintains full rail-to-rail output swing and 10.5 V/µs slew rate, as verified in TI's SLOS209G datasheet Section 5.
Does TLV2774AIDR support true rail-to-rail input?
No, TLV2774AIDR features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD −1.3 V (at 25°C), meaning the non-inverting input cannot accept signals within 1.3 V of VDD. This limitation is confirmed in the "Recommended Operating Conditions" table (Section 5) of the SLOS209G datasheet and applies across the full −40°C to 125°C range.
How does the shutdown functionality work on TLV2774AIDR?
TLV2774AIDR implements two independent active-low shutdown controls: pin 7 disables channels 1 and 2, while pin 14 disables channels 3 and 4. When pulled low (≤0.8 V), each control reduces the respective pair's supply current to <1 µA. Both controls must be high (>2.0 V) for full operation. This architecture is detailed in Figure 1 and Section 6.5 of the SLOS209G datasheet.
Is TLV2774AIDR pin-compatible with other TLV277x variants in SOIC-14?
Yes, TLV2774AIDR shares identical pinout and SOIC-14 footprint with TLV2774CDR, TLV2774IDR, and TLV2774CPW - all follow the standardized 14-pin layout shown in Figure 4 of SLOS209G. However, suffix differences (A, I, C) denote temperature grade and qualification; substituting non-A versions forfeits AEC-Q100 compliance and guaranteed 1.6 mV VIO max.
What is the typical THD+N performance of TLV2774AIDR at 1 kHz?
TLV2774AIDR achieves 0.005% THD+N at 1 kHz when driving a 600 Ω load with AV = 1 and VDD = 5 V, as measured in Section 7 (Operating Characteristics) of the SLOS209G datasheet. This value degrades to 0.016% at AV = 10 and remains ≤0.095% at AV = 100 - confirming suitability for high-fidelity audio and telecom line-driver applications.
