Product details
Overview
TLV2771IDBVT from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, high-speed signal conditioning in precision analog systems. 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 across a 2.5 V to 5.5 V supply range - enabling accurate ADC driving and telecom line driver applications in automotive and industrial environments.
For engineers reviewing the TLV2771IDBVT datasheet, TLV2771IDBVT pinout, TLV2771IDBVT application, or TLV2771IDBVT equivalent, key selection considerations include its −40°C to 125°C operating temperature range, SOT-23-5 package footprint, micropower shutdown mode (<1 µA), and verified rail-to-rail output swing into 600-Ω loads with 0.005% THD+N at 5 V.
Technical Context
The TLV2771IDBVT employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing and low-noise signal amplification. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust stability in active filter and buffer configurations.
It features internal rail-to-rail output stage capable of sourcing/sinking ±2.2 mA while maintaining <0.2 V headroom from rails at 5 V supply, and integrates a dedicated shutdown terminal (Pin 5) that reduces supply current to <1.5 µA without affecting input bias or offset performance during disabled state.

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. TLV2771IDBVT's 2 µV/°C; 350 kHz GBW vs. 5.1 MHz. | Better dc precision for long-term sensor calibration; lower speed limits use in active filters or fast-settling circuits. | Choose OPA333AIDBVR when ultra-low drift dominates over bandwidth; avoid where >1 MHz closed-loop bandwidth is required. |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs); higher input bias (1 pA typical but not guaranteed over temp); no shutdown pin. | Cost-optimized general-purpose replacement; lacks micropower shutdown and automotive temperature rating. | Choose MCP6001T-E/OT only for commercial-temp, non-shutdown, low-bandwidth applications where BOM cost is primary constraint. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, the TLV2771IDBVT uniquely balances high-speed performance (5.1 MHz, 10.5 V/µs), rail-to-rail output, integrated shutdown, and AEC-Q100–compatible temperature range - making it the only option among the three qualified for automotive signal chain designs requiring both precision and responsiveness.

FAQ
What is the maximum supply voltage for TLV2771IDBVT?
The absolute maximum supply voltage for TLV2771IDBVT is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks permanent damage and violates TI's specified conditions; sustained use at 6 V or higher is not supported and may degrade long-term reliability. Always refer to the Absolute Maximum Ratings table in the official TLV2771IDBVT datasheet for safe design margins.
Does TLV2771IDBVT support true rail-to-rail input?
No, TLV2771IDBVT does not feature rail-to-rail input - only rail-to-rail output. Its common-mode input voltage range extends from GND to VDD − 1.3 V at 5 V supply, meaning the maximum allowable input is 3.7 V. For applications requiring input signals near VDD, an external level-shifter or alternative op-amp with RRI capability (e.g., TLV9001) must be selected. This limitation is explicitly documented in the Recommended Operating Conditions table for TLV2771IDBVT.
What is the shutdown current of TLV2771IDBVT?
The shutdown current of TLV2771IDBVT is specified as 0.8 µA to 2 µA over the full −40°C to +125°C temperature range, with 1.5 µA typical at 25°C. This ultra-low IDD(SHDN) enables microampere-level system sleep modes while retaining fast wake-up response (turnon time <2.5 µs). The shutdown function is activated by pulling Pin 5 (SHDN) to ≤0.8 V; leaving it open or floating is not permitted and may cause undefined behavior.
Is TLV2771IDBVT pin-compatible with other SOT-23-5 op-amps?
TLV2771IDBVT uses the standard SOT-23-5 pinout (OUT, IN−, IN+, GND, SHDN), matching industry conventions for single-channel op-amps with shutdown. However, pin compatibility does not guarantee functional equivalence: competing parts may assign Pin 5 to NC, V−, or EN with opposite polarity. Always verify pin mapping against the specific alternative's datasheet before substitution - TLV2771IDBVT's SHDN pin is active-low and requires proper logic-level drive to avoid unintended shutdown.
What load capacitance can TLV2771IDBVT safely drive without oscillation?
TLV2771IDBVT is characterized for stability with up to 100 pF capacitive load when driving a 600-Ω resistor, achieving 46° phase margin per the datasheet's Operating Characteristics table. Driving larger capacitive loads (>150 pF) or purely capacitive loads without series resistance risks instability and ringing. For heavier loads, add a 10-Ω to 50-Ω isolation resistor between TLV2771IDBVT output and the capacitor - a technique validated in TI's Application Report SBAA212 for this device family.
