Product details
Overview
TLV2620IDBVR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier with shutdown, designed for low-power, wide-bandwidth signal conditioning 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 across –40°C to 125°C - ideal for precision sensor interfaces and portable data acquisition.
For engineers reviewing the TLV2620IDBVR datasheet, TLV2620IDBVR pinout, TLV2620IDBVR application, or TLV2620IDBVR equivalent, this page provides verified technical context, validated SOT-23-6 pin mapping, real-world use cases in Li-ion powered instrumentation, and confirmed alternative options for low-voltage, low-noise opamp selection.
Technical Context
The TLV2620IDBVR implements a CMOS input stage with rail-to-rail output swing and an input common-mode range extending to the positive 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 at AV = 1 with 2 kΩ load and 10 pF capacitance.
Shutdown functionality is controlled by a dedicated SHDN pin (Pin 6), reducing supply current to 4 µA per channel while maintaining fast enable/disable timing (t(on) = 4.5 µs at VDD = 2.7 V; t(off) = 200 ns). Phase margin is specified at 63° under standard test conditions, ensuring robust stability in unity-gain follower configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 11 MHz - supports stable closed-loop operation up to ~10 MHz in low-gain configurations with minimal phase lag. |
| Slew rate | 10 V/µs - enables clean 1-MHz, 10-VPP signal reproduction without slew-induced distortion. |
| Supply current per channel | 800 µA - allows battery-powered designs with multi-day runtime using coin-cell or Li-ion sources. |
| Input voltage noise | 27 nV/√Hz at 10 kHz - preserves SNR in front-end amplification of µV-level sensor outputs. |
| Common-mode input range | 1 V to VDD + 0.2 V - accommodates signals referenced to VDD (e.g., resistive bridge top-side excitation). |
| Shutdown current | 4 µA per channel - reduces system standby power by >99% versus active mode. |
| Operating temperature | –40°C to 125°C - qualified for industrial motor control, automotive cabin electronics, and harsh-environment monitoring. |
Pinout & Package
SOT-23-6 package (DBV), 1.45 mm max height, RoHS-compliant, NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | Differential node for feedback network connection; high-impedance CMOS input (IIB = 2 pA typ). |
| 2 - IN+ | Non-inverting input | High-impedance input accepting signals up to VDD + 0.2 V; enables rail-referenced sensing. |
| 3 - GND | Analog ground reference | Primary return path for input bias currents and output load; must be low-impedance for noise immunity. |
| 4 - VDD | Positive supply rail | Accepts 2.7 V to 5.5 V; powers internal biasing and output stage; decoupling capacitor required. |
| 5 - OUT | Amplifier output | Rail-to-rail capable (VOH = 2.67 V, VOL = 0.26 V @ VDD = 2.7 V, IO = ±10 mA). |
| 6 - SHDN | Active-low shutdown control | Pulls supply current to 4 µA when ≤0.4 V; logic-high (>2 V) enables full operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into 2-kΩ loads - maximizes ADC utilization and minimizes headroom loss in 3.3-V systems. |
| Positive-rail input capability | Supports direct connection to VDD-referenced transducers (e.g., half-bridge pressure sensors), eliminating level-shifting circuitry. |
| Ultra-low shutdown current | 4 µA per channel enables true "off" state in intermittent-sampling architectures like portable gas analyzers. |
| Wide supply range (2.7–5.5 V) | Operates across single Li-ion cell (3.0–4.2 V) and regulated 3.3-V rails - simplifies power architecture in mixed-voltage systems. |
| Industrial temperature grade | Specified performance over –40°C to 125°C ensures reliability in engine control units, solar inverters, and factory automation nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2630IDBVR | Lower input common-mode range (GND to VDD − 0.8 V); identical GBW (10 MHz), supply current (750 µA), and shutdown current (4 µA). | Not suitable for VDD-referenced inputs; requires input biasing for rail-sensing applications. | Select TLV2630IDBVR only when input signals stay ≥0.8 V below VDD and cost sensitivity outweighs rail-sensing flexibility. |
| OPA320AIDBVR | Higher precision (VIO = 150 µV max vs. 3500 µV), lower noise (10 nV/√Hz), but no shutdown and higher supply current (1.8 mA). | Lacks power-gating capability; unsuitable for duty-cycled sensor nodes requiring µA-level standby. | Choose OPA320AIDBVR for ultra-low-offset, low-noise measurement chains where continuous operation is mandatory and power budget permits. |
Compared with TLV2620IDBVR, TLV2630IDBVR trades positive-rail input capability for marginally lower quiescent current, while OPA320AIDBVR sacrifices shutdown and power efficiency for superior DC accuracy and noise performance - making TLV2620IDBVR the optimal balance for battery-constrained, rail-sensing applications.

FAQ
What is the maximum recommended supply voltage for TLV2620IDBVR?
The absolute maximum supply voltage for TLV2620IDBVR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and invalidates specifications; sustained use at 5.5 V is acceptable and commonly deployed in 5-V rail systems. The device is optimized for Li-ion (3.0–4.2 V) and regulated 3.3-V supplies.
Does TLV2620IDBVR support rail-to-rail input?
No, TLV2620IDBVR 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 signals down to 1 V above ground, not to GND. However, it does provide rail-to-rail output swing and uniquely supports inputs up to 0.2 V beyond VDD, enabling direct interface with VDD-referenced sources.
How does the shutdown function behave on TLV2620IDBVR?
The SHDN pin (Pin 6) is active-low: pulling it ≤0.4 V disables the amplifier and reduces supply current to 4 µA per channel; driving it ≥2 V enables normal operation. Turnon time is 4.5 µs (VDD = 2.7 V), and turnoff time is 200 ns. Output enters high-impedance state during shutdown, preventing loading of downstream circuitry.
Can TLV2620IDBVR drive capacitive loads reliably?
TLV2620IDBVR is characterized for stability with 10 pF capacitive load and 2-kΩ series resistance (RL = 2 kΩ, CL = 10 pF), achieving 63° phase margin. Driving larger capacitive loads (>100 pF) without isolation resistance may cause peaking or oscillation. For ADC driver applications with >50-pF input capacitance, a 10–100 Ω series resistor between TLV2620IDBVR output and ADC input is recommended to maintain stability.
What is the input offset voltage specification for TLV2620IDBVR over temperature?
TLV2620IDBVR has a maximum input offset voltage of 3500 µV at 25°C and 4500 µV over the full –40°C to 125°C range. Its typical offset drift is 3 µV/°C. This performance is appropriate for medium-precision applications such as sensor signal conditioning where post-calibration or ratiometric measurement compensates for offset; it is not intended for µV-level DC precision without trimming.
