Product details
Overview
TLV2632IDGKR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V, featuring 9 MHz gain-bandwidth product, 730 µA per channel supply current, −40°C to 125°C industrial temperature range, and ground-sensing input common-mode range (VICR = GND to VDD−1 V). It targets high-resolution data acquisition systems interfacing with ADCs in battery-powered instrumentation.
For engineers reviewing the TLV2632IDGKR datasheet, TLV2632IDGKR pinout, TLV2632IDGKR application, or TLV2632IDGKR equivalent, key selection criteria include its ultralow quiescent current at 2.7-V operation, rail-to-rail output swing enabling full dynamic range utilization, wide supply voltage compatibility with Li-ion cells and MSP430 microcontrollers, and MSOP-8 packaging for space-constrained PCB layouts.
Technical Context
The TLV2632IDGKR implements a CMOS input stage with rail-to-rail output stage, supporting unity-gain stable operation with load capacitance up to 50 pF. Its input common-mode range extends to ground, allowing direct connection to ground-referenced sensors and DAC outputs without level-shifting circuitry.
It delivers 9.5 V/µs negative slew rate and 6 V/µs positive slew rate at 5 V supply, with 50 nV/√Hz input voltage noise at 1 kHz and 0.003% THD+N at 10 kHz under AV = 1. The device maintains 67 dB minimum CMRR over its full operating temperature range and achieves 70 dB PSRR at DC.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2622IDGKR | Higher 11 MHz GBW but 750 µA/channel supply current; input range limited to 1 V above GND. | Not suitable for ground-referenced sensor inputs; better for higher-speed filtering where VICR > 1 V is guaranteed. | Select when bandwidth >9 MHz is required and input common-mode never approaches ground. |
| OPA2343UA | 5.5 MHz GBW, 850 µA/channel, rail-to-rail I/O, but only rated to 85°C ambient. | Lacks extended temperature qualification; unsuitable for under-hood or industrial control cabinet deployments. | Choose for cost-sensitive consumer-grade designs where 125°C operation is unnecessary. |
Compared with TLV2632IDGKR, TLV2622IDGKR trades ground-sensing capability for +2 MHz bandwidth, while OPA2343UA offers lower cost and comparable rail-to-rail performance but lacks industrial temperature support-making TLV2632IDGKR the optimal choice for dual-channel, ground-capable, high-temp precision signal conditioning.

FAQ
What is the maximum recommended supply voltage for TLV2632IDGKR?
The absolute maximum supply voltage for TLV2632IDGKR is 6 V, but the recommended operating range is strictly 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and violates TI's specified conditions; sustained use at 6 V is not supported. Designers should implement overvoltage protection if system rails may exceed 5.5 V transiently.
Does TLV2632IDGKR support true rail-to-rail input operation?
No, TLV2632IDGKR does not support rail-to-rail input. Its input common-mode voltage range is specified as GND to VDD−1 V - meaning it accepts signals down to ground but cannot handle inputs within 1 V of the positive rail. This differs from rail-to-rail input op-amps like the OPA333, which accept VICR from GND to VDD.
Can TLV2632IDGKR drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, TLV2632IDGKR guarantees rail-to-rail output swing into loads ≥10 kΩ across the full temperature range. At 10-mA load (e.g., 270 Ω at 2.7 V), output swing degrades to ~2.55 V high and ~0.15 V low - still usable but no longer rail-to-rail. For 10-kΩ loads, VOH ≥ VDD−0.08 V and VOL ≤ 0.03 V are ensured.
Is the exposed thermal pad on TLV2632IDGKR's VSSOP-8 package electrically connected?
Yes, the exposed PowerPAD™ on TLV2632IDGKR is internally connected to GND. TI's datasheet and package drawings confirm this connection, and proper PCB layout requires soldering the pad to a solid GND plane using ≥4 thermal vias to ensure optimal thermal performance and electrical stability.
What is the typical turn-on time for TLV2632IDGKR when exiting shutdown mode?
TLV2632IDGKR does not include a shutdown function - it is the non-shutdown dual variant in the TLV263x family. Only TLV2630 (single w/SHDN), TLV2633 (dual w/SHDN), and TLV2635 (quad w/SHDN) feature shutdown pins. TLV2632IDGKR operates continuously and has no enable/disable timing specification.
