Texas Instruments TLV2771AID

Overview

TLV2771AID from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for precision, low-power, and high-speed analog signal conditioning in automotive and industrial systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max), 1 mA supply current per channel, and operates from 2.5 V to 5.5 V. It drives ADC reference inputs and telecom line drivers with 0.005% THD+N into 600 Ω.

For engineers reviewing the TLV2771AID datasheet, TLV2771AID pinout, TLV2771AID application, or TLV2771AID equivalent, this page provides verified electrical specs, temperature-rated performance (−40°C to 125°C), SOT-23-5 package details, real-world use cases in sensor front-ends and automotive powertrain monitoring, and validated alternative options.

Technical Context

The TLV2771AID uses a CMOS input stage enabling ultra-low 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz. Its rail-to-rail output stage supports full-swing operation down to 0.1 V above GND and within 0.2 V of VDD at 2.2 mA load, critical for low-voltage ADC interface integrity.

It features micropower shutdown mode (<1 µA per channel) and is characterized across −40°C to 125°C with guaranteed 1.6 mV max input offset voltage and 2 µV/°C drift - meeting AEC-Q100 stress test requirements for automotive under-hood applications.

FAQ

What is the maximum operating temperature range for TLV2771AID?

The TLV2771AID is rated for continuous operation from −40°C to 125°C, with full electrical specifications guaranteed across this range. This makes it suitable for under-hood automotive applications such as engine control modules and transmission control units where ambient temperatures exceed 105°C. The "A" grade suffix explicitly denotes this extended temperature qualification per TI's internal standards.

Does TLV2771AID support rail-to-rail input capability?

No, TLV2771AID does not feature rail-to-rail input. Its common-mode input voltage range is specified from GND to VDD − 1.3 V at 2.7 V supply, meaning the input cannot swing within 1.3 V of the positive rail. However, its rail-to-rail output stage delivers full swing from GND to VDD, which is essential for maximizing dynamic range when driving ADC references or low-voltage loads.

What is the typical supply current of TLV2771AID at 3.3 V operation?

The TLV2771AID draws 1 mA per channel typical supply current across its full 2.5 V to 5.5 V supply range, including at 3.3 V. This value is confirmed in the Electrical Characteristics tables for both 2.7 V and 5 V conditions and remains stable across temperature (−40°C to 125°C). Shutdown mode reduces current to <1 µA, enabling ultra-low-power duty-cycled operation.

Is TLV2771AID pin-compatible with other devices in the TLV277x family?

TLV2771AID in SOT-23-5 (DBV) package shares identical pinout with TLV2771CD, TLV2771ID, and TLV2771CDBV - all follow the standard OUT–IN−–IN+–GND–VDD configuration. However, it is not pin-compatible with multi-channel variants (e.g., TLV2772) or shutdown-enabled versions (e.g., TLV2770), which use different pin counts and assignments. Always verify package marking and pin 1 orientation before PCB layout.

What load drive capability does TLV2771AID provide at 5 V supply?

At 5 V supply, TLV2771AID delivers ±4.2 mA output current while maintaining rail-to-rail swing: high-level output is ≥4.7 V at −4.2 mA, and low-level output is ≤0.21 V at +4.2 mA. This supports direct driving of 600 Ω telecom lines, 10 kΩ ADC reference inputs, and moderate-current sensor excitation circuits without external buffers - reducing bill-of-materials count in space-constrained designs.
