Product details
Overview
TLV2771CDBVR from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, low-power precision applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA supply current per channel, and operates from 2.5 V to 5.5 V - enabling high-fidelity signal conditioning in portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2771CDBVR datasheet, TLV2771CDBVR pinout, TLV2771CDBVR application, or TLV2771CDBVR equivalent, key selection considerations include its SOT-23-5 package footprint, micropower shutdown mode (<1 µA), 17 nV/√Hz input noise, and guaranteed performance across 0°C to 70°C ambient temperature.
Technical Context
The TLV2771CDBVR employs a CMOS input stage with 2 pA input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfacing. Its rail-to-rail output stage drives loads down to 600 Ω while maintaining 0.005% THD+N at 1 kHz - critical for telecom line drivers and ADC reference buffers.
It features internal compensation for unity-gain stability, 46° phase margin with 600 Ω load and 100 pF capacitance, and operates with no external components required. The device includes a dedicated shutdown pin (SHDN) enabling fast turnoff (345 ns typical) and ultra-low quiescent current during sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth into 10 kΩ. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop gain ≥ 10 at 500 kHz with adequate phase margin. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤ 3.6 mV error in unity-gain buffer configurations over industrial temperature range. |
| Supply Current | 1 mA per channel - allows continuous operation for >1000 hours on a 1000 mAh Li-ion cell in always-on sensing nodes. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - contributes <1.7 µV RMS noise in 100 kHz bandwidth, suitable for 16-bit ADC front-ends. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes dynamic range when interfacing with 3.3 V or 5 V SAR ADCs. |
| Shutdown Current | <1 µA - reduces system standby power by >99.9% versus active mode, enabling long-term battery storage. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified single-ended output node; capable of sourcing/sinking ±2.2 mA while maintaining rail-to-rail swing. |
| 2 (IN−) | Inverting Input | Differential input terminal; 2 pA bias current enables high-Z source interfacing without significant error. |
| 3 (IN+) | Non-inverting Input | Differential input terminal; matched to IN− for optimal common-mode rejection (84 dB min). |
| 4 (GND) | Analog Ground | Reference return path for input and output stages; must be low-impedance to minimize noise coupling. |
| 5 (SHDN) | Shutdown Control | Active-high logic input; pulls supply current to <1 µA when driven ≥1.4 V (VDD = 2.7 V) or ≥2.4 V (VDD = 5 V). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2771CDBVR's 2 µV/°C; higher cost; 17 µA supply current. | Better for DC-critical applications like precision weigh scales; unsuitable for low-power battery operation. | Select OPA333AIDBVR only when offset drift dominates error budget and power is secondary. |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs); wider supply range (1.8–6.0 V); no shutdown pin; 100 nA input bias current. | Cost-optimized for general-purpose sensing; lacks rail-to-rail output drive capability into 600 Ω loads. | Choose MCP6001T-E/OT for non-critical, low-cost consumer electronics where speed and THD+N are not constrained. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, the TLV2771CDBVR uniquely balances high-speed precision (10.5 V/µs, 5.1 MHz) with micropower operation (1 mA) and integrated shutdown - making it the optimal choice for portable, battery-constrained systems requiring both bandwidth and accuracy.

FAQ
What is the maximum supply voltage rating for TLV2771CDBVR?
The absolute maximum supply voltage for TLV2771CDBVR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates TI's specified conditions; sustained use at 7 V is prohibited even for transient events. Always refer to the Absolute Maximum Ratings table in the SLOS209G datasheet for safe design margins.
Does TLV2771CDBVR support true rail-to-rail input operation?
No, TLV2771CDBVR features rail-to-rail *output* swing only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V), meaning it cannot accept signals at the positive rail. For full rail-to-rail input capability, consider alternatives like the TLV9001 or OPA320 series.
How does the shutdown pin (SHDN) function on TLV2771CDBVR?
The SHDN pin on TLV2771CDBVR is active-high: driving it ≥1.4 V (at VDD = 2.7 V) or ≥2.4 V (at VDD = 5 V) disables the amplifier and reduces supply current to <1 µA. Pulling SHDN low or leaving it unconnected (with internal pull-down) enables normal operation. No external pull-up is required for default-enable behavior.
Can TLV2771CDBVR drive a 600 Ω load while maintaining low distortion?
Yes - TLV2771CDBVR is specifically characterized for 0.005% THD+N when driving a 600 Ω load at 1 kHz, confirming its suitability for telecom line drivers and audio codec interfaces. This performance is guaranteed under VDD = 5 V, AV = 1, and RL = 600 Ω conditions per the SLOS209G datasheet Section 7.
Is TLV2771CDBVR qualified for automotive applications?
No - TLV2771CDBVR carries the 'C' temperature suffix (0°C to 70°C), indicating commercial-grade qualification. Automotive-grade variants exist (e.g., TLV2771QDBVR, Q-suffix, −40°C to 125°C), but TLV2771CDBVR itself is not AEC-Q100 qualified and lacks automotive-specific testing or documentation.
