Product details
Overview
TLV2620ID 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 TLV2620ID datasheet, TLV2620ID pinout, TLV2620ID application, or TLV2620ID equivalent, key selection criteria include its rail-to-rail output swing, positive-rail-inclusive input common-mode range (1 V to VDD + 0.2 V), ultralow 4 µA shutdown current, and SOT-23-6 packaging for space-constrained designs.
Technical Context
The TLV2620ID uses a CMOS input stage enabling picoampere-level input bias current (2–50 pA) and high differential input resistance (100 GΩ), supporting high-impedance source interfacing. Its rail-to-rail output stage maintains >28 mA drive capability while delivering full-swing performance into 2 kΩ loads at both 2.7 V and 5 V supplies.
Integrated shutdown control (SHDN pin) reduces quiescent current to 4 µA per channel without compromising turn-on time (≤4.5 µs at VDD = 2.7 V) or phase margin (63° at CL = 10 pF), ensuring stable operation in battery-powered systems requiring dynamic power gating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2621IDBVR | 5-pin SOT-23; no shutdown pin; identical AC/DC specs except SHDN omission | Used where continuous operation is required and board space must be minimized further | Select when shutdown functionality is unnecessary and pin count reduction is prioritized |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift; 17 µV max offset; 350 kHz GBW; 17 µA supply current | Preferred for ultra-low-offset DC applications (e.g., weigh scales), not high-speed signal chains | Choose for sub-µV offset stability over temperature; avoid when >1 MHz bandwidth is required |
Compared with TLV2621IDBVR, TLV2620ID adds shutdown control at the cost of one pin; compared with OPA333AIDBVR, it trades zero-drift precision for 31× higher bandwidth and 47× lower quiescent current - making TLV2620ID optimal for battery-powered, medium-precision, wideband signal paths.

FAQ
What is the maximum recommended supply voltage for TLV2620ID?
The absolute maximum supply voltage for TLV2620ID 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 violates the device's qualified specifications. At 5.5 V, the amplifier maintains full rail-to-rail output swing and meets all AC/DC performance parameters listed in the SLOS251D datasheet.
Does TLV2620ID support rail-to-rail input?
No, TLV2620ID 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 cannot handle signals near GND. However, it does provide true rail-to-rail output swing, delivering voltages within 0.2 V of both supply rails under rated load conditions.
What is the typical turn-on time for TLV2620ID from shutdown mode?
The typical amplifier turn-on time for TLV2620ID is 4.5 µs when VDD = 2.7 V and RL = 2 kΩ, defined as the interval between SHDN rising to ≥2 V and supply current reaching 50% of its active value (800 µA). At VDD = 5 V, turn-on time reduces to 1.5 µs. This fast wake-up supports burst-mode sampling in energy-constrained systems.
Can TLV2620ID drive capacitive loads directly?
TLV2620ID is stable with up to 10 pF capacitive load when configured as a unity-gain buffer (RL = 2 kΩ), maintaining 63° phase margin. Driving larger capacitive loads (e.g., >50 pF) requires isolation resistance (≥100 Ω) in series with the output to prevent peaking or oscillation - confirmed by Figure 16 (Phase Margin vs Load Capacitance) in the SLOS251D datasheet.
Is TLV2620ID RoHS compliant and lead-free?
Yes, TLV2620ID is RoHS compliant and lead-free. Per TI's Package Option Addendum, the TLV2620ID part number corresponds to the SOIC-8 (D) package with Green (RoHS & no Sb/Br) eco plan, CU NIPDAU terminal finish, and JEDEC MSL Level-1 rating. All active orderable variants (e.g., TLV2620IDR) meet IPC/JEDEC J-STD-609 Category 1 requirements.
