Product details
Overview
TLV2621IDBVR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for low-power, wide-bandwidth applications in single-supply systems. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA supply current per channel, and operates from 2.7 V to 5.5 V over –40°C to +125°C - enabling use in battery-powered data acquisition front-ends and precision sensor signal conditioning.
For engineers reviewing the TLV2621IDBVR datasheet, TLV2621IDBVR pinout, TLV2621IDBVR application, or TLV2621IDBVR equivalent, this page provides verified electrical specifications, SOT-23-5 package terminal mapping, industrial-grade temperature performance, shutdown functionality timing, and validated alternative op-amps for low-voltage, low-noise, high-speed analog signal paths.
Technical Context
The TLV2621IDBVR employs a CMOS input stage with rail-to-rail output swing and an input common-mode range extending to the positive supply rail (VICR = 1 V to VDD + 0.2 V), enabling direct interfacing with high-side referenced sensors and ADC reference buffers. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate support stable operation driving 2-kΩ loads with 10-pF capacitive loads at 2.7 V and 5 V supplies.
Internal shutdown control reduces supply current to 4 µA/channel while maintaining fast enable/disable timing (ton = 4.5 µs at 2.7 V; toff = 200 ns). Phase margin remains ≥63° across operating conditions, ensuring robust stability in unity-gain follower and active filter configurations without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2631IDBVR | Lower input common-mode range (GND to VDD − 0.8 V); identical GBW (10 MHz), supply current (750 µA), and noise (27 nV/√Hz) | Not suitable for VDD-referenced inputs; requires input biasing network for high-side sensors | Select when input signals stay within GND–VDD range and cost sensitivity outweighs rail-inclusive input requirement |
| OPA320AIDBVR | Higher precision (VIO = 150 µV max vs. 3500 µV), lower noise (7 nV/√Hz), higher supply current (1.8 mA), no shutdown | Better for DC-critical applications (e.g., weigh scales); unsuitable where ultra-low standby power is mandatory | Choose when offset and noise dominate design constraints and shutdown functionality is unnecessary |
Compared with TLV2621IDBVR, TLV2631IDBVR trades rail-inclusive input for slightly lower power but loses direct high-side interface capability, while OPA320AIDBVR improves DC accuracy and noise at 2.25× higher active current and no power-down mode - making TLV2621IDBVR optimal for battery-constrained, wide-dynamic-range, high-temperature signal conditioning.

FAQ
What is the maximum recommended supply voltage for TLV2621IDBVR?
The absolute maximum supply voltage for TLV2621IDBVR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage, while operation at 2.7 V maintains full 11-MHz bandwidth and rail-to-rail output swing - making TLV2621IDBVR ideal for lithium-ion and coin-cell powered designs.
Does TLV2621IDBVR support rail-to-rail input?
No, TLV2621IDBVR does not support rail-to-rail input. Its common-mode input voltage range is specified from 1 V to VDD + 0.2 V - meaning it accepts inputs down to 1 V above ground, but not to GND. However, it does provide true rail-to-rail output swing, and its positive-rail–inclusive input enables direct connection to VDD-referenced sources, a key differentiator versus standard op-amps.
How fast does TLV2621IDBVR exit shutdown mode?
TLV2621IDBVR has a typical turn-on time (ton) of 4.5 µs at VDD = 2.7 V and 1.5 µs at VDD = 5 V, measured from SHDN logic low-to-high transition to supply current reaching 50% of active value. This fast wake-up enables burst-mode sampling in energy-constrained systems without introducing latency penalties in real-time signal chains.
What is the output drive capability of TLV2621IDBVR?
TLV2621IDBVR delivers ±28 mA output current at VDD = 5 V and ±14 mA at VDD = 2.7 V, with rail-to-rail swing into 2-kΩ loads (VOH = 4.98 V, VOL = 0.025 V at 5 V; VOH = 2.67 V, VOL = 0.26 V at 2.7 V). This allows direct driving of ADC references, LED indicators, or small MOSFET gates without external buffers.
Is TLV2621IDBVR suitable for automotive applications?
Yes, TLV2621IDBVR is qualified for the extended industrial temperature range of –40°C to +125°C and carries TI's standard automotive-grade reliability testing. While not AEC-Q200 certified out-of-box, its robust parametric performance across this range - including stable phase margin, low drift, and shutdown integrity - makes it widely deployed in non-safety-critical automotive cabin modules such as seat occupancy sensors, ambient light controls, and HVAC feedback circuits.
