Product details
Overview
TLV2771QDBVRQ1 from Texas Instruments is an automotive-grade, single-channel CMOS operational amplifier with rail-to-rail output, 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and micropower shutdown mode (IDD < 1 µA). It operates from 2.5 V to 5.5 V, delivers 360 µV max input offset voltage, and is qualified per AEC-Q100 Grade 1 (−40°C to 125°C) for use in engine control sensor signal conditioning.
For engineers reviewing the TLV2771QDBVRQ1 datasheet, TLV2771QDBVRQ1 pinout, TLV2771QDBVRQ1 application, or TLV2771QDBVRQ1 equivalent, key selection criteria include its high-speed rail-to-rail output drive into 600 Ω loads (0.005% THD+N), low 17 nV/√Hz input noise, and guaranteed performance across extended temperature and supply voltage ranges - critical for automotive analog front-ends and precision ADC driver stages.
Technical Context
The TLV2771QDBVRQ1 implements a CMOS input stage with 2 pA typical input bias current and 10¹² Ω differential input resistance, enabling high-impedance sensor interfacing. Its unity-gain-stable architecture supports fast settling (1.97 µs to 0.01%) and maintains 46° phase margin with 600 Ω load and 100 pF capacitance.
It features a dedicated shutdown pin (SHDN) that reduces supply current to <1 µA while preserving rail-to-rail output capability on wake-up. The device is characterized at both 2.7 V and 5 V supplies, with input common-mode range extending to GND and output swing within 100 mV of rails under 2.2 mA load.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Dual-channel, higher supply current (2.3 mA/ch), no shutdown, wider supply (2.7–36 V) | Supports bipolar supplies and higher-voltage actuator interfaces; lacks micropower shutdown | Choose when dual-channel operation and high-voltage tolerance outweigh shutdown need |
| TSV911IQDBVRQ1 | Lower slew rate (4.5 V/µs), lower GBW (8 MHz), same shutdown, lower offset (150 µV max) | Better dc precision but insufficient bandwidth for fast sensor transients (>200 kHz) | Prefer for ultra-low-offset, low-speed automotive signal chains where speed is secondary |
Compared with LM7332QMA/NOPB and TSV911IQDBVRQ1, the TLV2771QDBVRQ1 uniquely balances high-speed (10.5 V/µs), rail-to-rail output, micropower shutdown (<1 µA), and AEC-Q100 Grade 1 qualification - making it optimal for space-constrained, battery-sensitive automotive sensor nodes requiring fast, precise, and robust analog signal conditioning.

FAQ
What is the maximum operating temperature range for TLV2771QDBVRQ1?
The TLV2771QDBVRQ1 is qualified per AEC-Q100 Grade 1 and operates reliably from −40°C to +125°C ambient temperature. This range is fully characterized for all electrical parameters including input offset voltage, slew rate, and supply current - enabling direct placement in engine control units without derating.
Does TLV2771QDBVRQ1 support true rail-to-rail input?
No, the TLV2771QDBVRQ1 features rail-to-rail *output* only. Its input common-mode voltage range extends to GND but does not include VDD - specified as 0 V to (VDD − 1.3 V) at 25°C. For full rail-to-rail input capability, consider TI's TLV9001QDBVRQ1 instead.
What is the shutdown current consumption of TLV2771QDBVRQ1?
In shutdown mode, the TLV2771QDBVRQ1 draws less than 1 µA total supply current (IDD < 1 µA) across the full −40°C to 125°C temperature range. This enables ultra-low-power duty-cycled operation in always-on automotive subsystems such as tire pressure monitoring or occupancy detection.
Can TLV2771QDBVRQ1 drive a 600-Ω load with low distortion?
Yes - the TLV2771QDBVRQ1 delivers 0.005% THD+N at 1 kHz into a 600-Ω load, verified per datasheet test conditions. This performance is enabled by its 10.5 V/µs slew rate and rail-to-rail output stage, making it suitable for telecom line drivers and high-fidelity sensor interfaces.
Is TLV2771QDBVRQ1 pin-compatible with other SOT-23-5 op-amps?
No - the TLV2771QDBVRQ1 uses a non-standard SOT-23-5 pinout: Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = GND, Pin 5 = VDD. It is not pin-compatible with industry-standard pinouts (e.g., MCP6001, LMV321), requiring dedicated PCB layout.
