Product details
Overview
TLV2771IDR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for low-voltage, high-speed precision applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and 1 mA supply current per channel while operating from 2.5 V to 5.5 V - enabling use in battery-powered sensor front-ends and ADC driver stages.
For engineers reviewing the TLV2771IDR datasheet, TLV2771IDR pinout, TLV2771IDR application, or TLV2771IDR equivalent, key selection criteria include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), micropower shutdown mode (<1 µA), and guaranteed operation across −40°C to +125°C for automotive and industrial signal conditioning.
Technical Context
The TLV2771IDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance source interfacing without significant error. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust performance in active filter and transimpedance configurations.
It features internal compensation and is characterized at both 2.7 V and 5 V supply voltages, with rail-to-rail output swing delivering >2.4 V high-level and <0.21 V low-level output voltage into 4.2 mA loads - critical for driving SAR ADC reference inputs and analog multiplexers in mixed-signal systems.

Pinout & Package
TLV2771IDR is packaged in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is marked by a beveled edge or molded dot; the device has no internal connection on pin 5 (SHDN not implemented).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - capable of sourcing/sinking ±4.2 mA while maintaining rail-to-rail swing. |
| 2 | IN− | Inverting input - high-impedance CMOS node (10¹² Ω) suitable for precision feedback networks. |
| 3 | IN+ | Non-inverting input - matched to IN− for optimal common-mode rejection and offset cancellation. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground in mixed-signal PCBs. |
| 5 | VDD | Positive supply - accepts 2.5 V to 5.5 V; no shutdown function present in TLV2771IDR variant. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 10 µV max offset; 350 kHz GBW; 17 µA supply current | Better dc precision but lower speed - suited for weigh scales, not high-frequency ADC drivers | Select TLV2771IDR for bandwidth-critical 500 kHz+ signal paths; choose OPA333AIDBVR only if sub-10 µV offset dominates design priority |
| MCP6001T-I/OT | Lower slew rate (0.6 V/µs); 1 MHz GBW; 100 µA supply current; same SOT-23-5 package | Optimized for ultra-low power, not speed - appropriate for slow-moving sensor outputs (e.g., pH probes) | TLV2771IDR provides 17× higher slew rate and 5× more bandwidth than MCP6001T-I/OT - essential for time-critical sampling systems |
Compared with OPA333AIDBVR and MCP6001T-I/OT, TLV2771IDR uniquely balances high-speed performance (10.5 V/µs, 5.1 MHz) with rail-to-rail output and 1 mA quiescent current - making it the only option among the three suitable for driving 1 MSPS+ SAR ADCs from a single 3.3 V rail without external level translation.

FAQ
What is the maximum supply voltage for TLV2771IDR?
The absolute maximum supply voltage for TLV2771IDR 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 parametric guarantees. At 5 V, TLV2771IDR delivers full-rated slew rate (10.5 V/µs) and output drive capability (±4.2 mA), making 5 V the optimal upper limit for performance-critical designs.
Does TLV2771IDR support shutdown mode?
No, TLV2771IDR does not include a shutdown function. The TLV2771 family variant with shutdown is TLV2771CDBVR or TLV2771IDBV - both in SOT-23-6 packages with dedicated SHDN pin. TLV2771IDR uses the 5-pin SOT-23 (DBV) package where pin 5 is unconnected; shutdown capability is absent by design and cannot be enabled via external circuitry.
What is the input common-mode voltage range for TLV2771IDR?
At VDD = 5 V, the input common-mode voltage range for TLV2771IDR is GND to (VDD − 1.3 V), i.e., 0 V to 3.7 V. This range is specified across the full operating temperature range (−40°C to +125°C). Inputs outside this range may cause phase reversal or increased offset error; for rail-to-rail input capability, consider TLV2461 or OPA333 instead.
Can TLV2771IDR drive a 600-Ω load with low distortion?
Yes, TLV2771IDR is explicitly characterized for 600-Ω loads: total harmonic distortion plus noise (THD+N) is 0.005% at 1 kHz with AV = 1, meeting telecom line-driver standards. It sustains this performance while delivering rail-to-rail output swing - verified at both 2.7 V and 5 V supplies. For sustained 600-Ω loading, ensure PCB layout minimizes trace inductance and uses local 100-nF bypass capacitance at VDD pin.
Is TLV2771IDR qualified for automotive applications?
Yes, TLV2771IDR carries the "I" temperature suffix (−40°C to +125°C) and is manufactured under TI's automotive qualification process, including AEC-Q100 stress testing. It appears in TI's Q-Temp Automotive documentation and is approved for use in body electronics, cabin climate control, and non-safety-critical ADAS subsystems - though not certified for ASIL-B or higher safety integrity levels.
