Product details
Overview
TLV2771CDBVT from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 17 nV/√Hz input noise, and operates from 2.5 V to 5.5 V supply - enabling high-fidelity analog front-end design in portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2771CDBVT datasheet, TLV2771CDBVT pinout, TLV2771CDBVT application, or TLV2771CDBVT equivalent, key selection considerations include its SOT-23-5 package footprint, micropower shutdown mode (<1 µA), rail-to-rail output swing into 600-Ω loads with 0.005% THD+N, and guaranteed operation across 0°C to 70°C ambient temperature.
Technical Context
The TLV2771CDBVT employs a CMOS input stage with 2 pA input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfacing. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust stability in driving ADC reference inputs or active filters.
It integrates a dedicated shutdown control (SHDN) pin enabling fast turnoff (t(OFF) = 444 ns) and wake-up (t(ON) = 2.4 µs), while maintaining rail-to-rail output swing (VOH ≥ 4.8 V, VOL ≤ 0.2 V at VDD = 5 V, IOL/IOH = 4.2 mA) - critical for single-supply 12-bit+ SAR ADC driver applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2771CDBVT's 2 µV/°C; 17 µV max offset vs. 360 µV | Better for DC-critical applications (e.g., weigh scales); higher cost and 1.6x supply current (1.6 mA) | Select when long-term DC stability outweighs power budget constraints |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs); lower GBW (1 MHz); no shutdown pin; 100 µV max offset | Suitable for low-speed sensor interfaces (e.g., temperature RTDs); lacks drive strength for 600-Ω telecom loads | Select for cost-sensitive, non-critical AC performance applications where shutdown is unnecessary |

FAQ
What is the operating temperature range for the TLV2771CDBVT?
The TLV2771CDBVT is characterized for operation from 0°C to 70°C (C-suffix grade). It is fully specified across this range for all key parameters including input offset voltage, supply current, and slew rate - making it suitable for commercial and industrial environments without thermal derating.
Does the TLV2771CDBVT support true rail-to-rail input capability?
No, the TLV2771CDBVT features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at VDD = 5 V), meaning the noninverting input cannot accept signals within 1.3 V of the positive rail - a design trade-off enabling high-speed CMOS input stage performance.
How does the shutdown function operate on the TLV2771CDBVT?
The TLV2771CDBVT's SHDN pin (Pin 5) is active-high: driving it high enables normal operation (IDD ≈ 1 mA), while pulling it low disables the amplifier core and reduces supply current to <1.5 µA. The device achieves turnoff in 444 ns and wake-up in 2.4 µs - ideal for burst-mode signal acquisition.
Can the TLV2771CDBVT drive a 600-Ω load with low distortion?
Yes, the TLV2771CDBVT is explicitly characterized for 0.005% THD+N into a 600-Ω load at 1 kHz (VDD = 5 V), meeting ITU-T G.712 telecom line driver specifications. Its 10.5 V/µs slew rate and rail-to-rail output ensure clean large-signal delivery without clipping or slewing-induced distortion.
What is the maximum supply voltage rating for the TLV2771CDBVT?
The absolute maximum supply voltage for the TLV2771CDBVT is 7 V, but its recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks exceeding internal junction temperature limits and invalidates parametric guarantees - TI specifies all electrical characteristics only within the 2.5–5.5 V range.
