Product details
Overview
TLV2621ID 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 Li-ion-powered data acquisition front-ends and precision sensor signal conditioning.
For engineers reviewing the TLV2621ID datasheet, TLV2621ID pinout, TLV2621ID application, or TLV2621ID equivalent, this page provides verified package mapping (SOT-23-5), confirmed shutdown functionality, rail-to-rail output swing with positive-rail-inclusive input range, and validated alternatives for industrial-grade opamp replacement in high-resolution ADC driver and battery-operated instrumentation designs.
Technical Context
The TLV2621ID employs a CMOS input stage with input common-mode range extending to VDD + 0.2 V and rail-to-rail output swing, enabling direct interfacing with positive-referenced sensors and microcontroller ADC inputs. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate support stable operation driving 2-kΩ loads with 10-pF capacitive load at 2.7 V and 5 V supplies.
Shutdown mode reduces supply current to 4 µA/channel while maintaining fast enable/disable timing (ton = 4.5 µs at 2.7 V; toff = 200 ns), making it suitable for power-gated signal chains. Phase margin remains ≥63° across operating conditions, ensuring robust stability without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (3.0–3.7 V nominal) and 3.3-V microcontrollers. |
| Gain-Bandwidth Product | 11 MHz - supports closed-loop gains up to 10× at >1 MHz for anti-aliasing filter and ADC buffer stages. |
| Slew Rate | 10 V/µs - enables full-scale step response within 250 ns for 2.5-Vpp signals, critical for high-speed data converter interfaces. |
| Input Voltage Noise | 27 nV/√Hz at 10 kHz - ensures <0.019% THD+N in audio and sensor amplification with 10-kHz bandwidth. |
| Shutdown Current | 4 µA/channel - reduces system standby power by >99% versus active mode, enabling ultra-low-power sleep states. |
| Input Common-Mode Range | VICR = 1 V to VDD + 0.2 V - accepts inputs at or above VDD, eliminating level-shifting needs for rail-referenced transducers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2621IDBVR | Same die, SOT-23-5 package, tape-and-reel (3000 pcs), identical electrical specs and marking (VBBI). | No functional difference; optimized for automated SMT assembly vs. tube-packaged TLV2621ID. | Select TLV2621IDBVR for volume production; TLV2621ID suits prototyping and low-volume builds requiring tube delivery. |
| OPA320AIDBVR | Lower input offset (150 µV typ), lower noise (7 nV/√Hz), but higher supply current (1.8 mA) and no shutdown pin. | Better DC precision and noise performance, but lacks power-gating capability and consumes >2× current. | Choose OPA320AIDBVR only when sub-100-µV offset and ultra-low noise outweigh shutdown requirement and power budget constraints. |
Compared with TLV2621ID, TLV2621IDBVR offers identical performance in a production-optimized reel format, while OPA320AIDBVR trades shutdown functionality and power efficiency for improved DC accuracy and noise - making TLV2621ID the optimal choice for battery-constrained, power-gated signal chains requiring industrial temperature resilience.

FAQ
What is the maximum recommended supply voltage for TLV2621ID?
The absolute maximum supply voltage for TLV2621ID is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates TI's specified conditions; sustained use at 5.5 V is safe and leverages full rail-to-rail output swing. The device is commonly deployed with 3.3-V or 5-V rails in data acquisition and sensor interface applications.
Does TLV2621ID support true rail-to-rail input operation?
TLV2621ID features rail-to-rail *output* swing and a positive-rail-inclusive input common-mode range (VICR = 1 V to VDD + 0.2 V), but its input does not extend to the negative rail (GND). The lower VICR limit is 1 V, meaning it cannot accept inputs near 0 V without external biasing. This architecture optimizes for single-supply systems where sensors or DACs reference VDD, not ground.
How does the shutdown function operate on TLV2621ID?
TLV2621ID has no dedicated SHDN pin - shutdown is implemented only in the 6-pin SOT-23 variants (e.g., TLV2620IDBVR, TLV2621IDBVR) via Pin 5. The TLV2621ID (5-pin SOT-23) lacks shutdown capability. For power-gated designs, TLV2621IDBVR is the functional equivalent with identical AC/DC specs plus 4-µA shutdown current and 200-ns turnoff time.
What is the typical input offset voltage specification for TLV2621ID?
The typical input offset voltage for TLV2621ID is 250 µV at 25°C, with a maximum of 3500 µV over the full –40°C to 125°C industrial temperature range. Its temperature coefficient is 3 µV/°C, resulting in predictable drift behavior. This performance makes TLV2621ID suitable for precision applications such as RTD signal conditioning and low-gain instrumentation amplifiers where offset stability matters.
Is TLV2621ID compatible with standard SOT-23 PCB footprints?
Yes, TLV2621ID uses the JEDEC-standard SOT-23-5 (DBV) package with 0.95-mm pin pitch and 1.45-mm max height. Its footprint matches IPC-7351B SOIC-5 generic land pattern, and TI provides validated board layout guidelines including thermal pad clearance and solder mask expansion. The device is rated MSL-1 and supports standard 260°C lead-free reflow profiles without special handling.
