Product details
Overview
TLV2452CDGKR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, and 23 µA/channel supply current across 2.7 V to 6 V operation - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452CDGKR datasheet, TLV2452CDGKR pinout, TLV2452CDGKR application, or TLV2452CDGKR equivalent, key selection criteria include its 8-pin MSOP package, shutdown capability (not present in this variant), rail-to-rail I/O swing within 250 mV of rails at 2.5 mA load, and guaranteed −40°C to 125°C operation for industrial-grade reliability.
Technical Context
The TLV2452CDGKR implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, supporting single-supply operation down to 2.7 V. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at 5 V with 10 kΩ load and 150 pF capacitance.
It features 106 dB power supply rejection ratio (PSRR), 89 dB common-mode rejection ratio (CMRR), and 20 µV typical input offset voltage - all validated across the full industrial temperature range. No internal shutdown control is integrated; the TLV2452 variant lacks SHDN pins per family documentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2452IDGKR | Same electrical specs but rated for −40°C to 125°C (I-suffix); TLV2452CDGKR is C-suffix (0°C to 70°C) | Required for automotive or extended-temperature industrial deployments where ambient exceeds 70°C | Select TLV2452IDGKR if operating temperature exceeds 70°C; otherwise TLV2452CDGKR suffices for commercial-grade portable gear |
| OPA2333AIDGKR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2452's 0.3 µV/°C; 35 µA/channel vs. 23 µA | Better long-term DC stability for high-precision weigh scales or strain gauge bridges; higher current draw | Choose OPA2333AIDGKR when sub-µV drift over temperature is mandatory; accept 52% higher supply current |
Compared with TLV2452CDGKR, TLV2452IDGKR extends temperature range without altering performance or pinout, while OPA2333AIDGKR trades ultralow power for near-zero drift - making TLV2452CDGKR optimal for cost-sensitive, battery-constrained applications needing robust 0–70°C operation.

FAQ
What is the operating temperature range for TLV2452CDGKR?
The TLV2452CDGKR is specified for 0°C to 70°C ambient operation (C-suffix grade). It maintains full electrical performance - including 23 µA/channel supply current, 220 kHz gain-bandwidth, and rail-to-rail I/O - across this commercial temperature range. For extended industrial use, TI offers the TLV2452IDGKR (−40°C to 125°C).
Does TLV2452CDGKR include a shutdown feature?
No, TLV2452CDGKR does not include a shutdown function. Per TI's family documentation, only TLV2450, TLV2453, and TLV2455 variants integrate shutdown terminals. The TLV2452CDGKR has no SHDN pin and draws 23 µA/channel continuously - making it ideal for always-on, low-duty-cycle sensor interfaces where shutdown adds complexity without benefit.
What package type is used for TLV2452CDGKR?
TLV2452CDGKR uses an 8-pin MSOP (Micro Small Outline Package) with DGK designation - 3.0 mm × 3.0 mm body, 0.65 mm lead pitch, and exposed thermal pad. This compact footprint supports high-density PCB layouts in space-constrained portable devices while providing adequate thermal dissipation for its 23 µA/channel operation.
Can TLV2452CDGKR operate from a single 3.3 V supply?
Yes, TLV2452CDGKR is fully specified for single-supply operation from 2.7 V to 6 V, including 3.3 V. At 3.3 V, it delivers rail-to-rail input (0 V to 3.3 V common-mode range) and output swing (within 250 mV of rails at 2.5 mA load), 220 kHz gain-bandwidth, and 23 µA/channel supply current - meeting requirements for low-voltage precision analog signal chains.
What is the input offset voltage specification for TLV2452CDGKR?
The TLV2452CDGKR has a typical input offset voltage of 20 µV at 25°C, with a maximum of 1300 µV across the full 0°C to 70°C operating range. This low offset enables high-accuracy DC amplification in applications such as thermistor signal conditioning and bridge sensor readouts where offset-induced errors must remain below 0.1% of full-scale.
