Product details
Overview
TLV2452IDGKR 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, with 20 µV typical input offset voltage and 106 dB PSRR - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452IDGKR datasheet, TLV2452IDGKR pinout, TLV2452IDGKR application, or TLV2452IDGKR equivalent, key selection criteria include its 8-pin MSOP package, shutdown-inactive design (no SHDN pin), −40°C to 125°C industrial temperature rating, rail-to-rail swing under 2.5-mA load, and verified performance at 3 V/5 V single-supply operation.
Technical Context
The TLV2452IDGKR operates as a dual-channel voltage amplifier with fully rail-to-rail input common-mode range (0 V to VDD) and output swing within 250 mV of each rail under 2.5-mA load. Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF capacitive loads and achieves 0.11 V/µs slew rate at 5 V supply.
It features no shutdown functionality - confirmed by family documentation stating only TLV2450/2453/2455 include SHDN pins, and TLV2452 pinout diagrams showing no shutdown terminal. Electrical specifications are fully characterized across −40°C to 125°C (I-suffix) and validated for single-supply use from 2.7 V to 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - delivers rail-to-rail voltage with ±10 mA sourcing/sinking capability |
| 2 | IN− A | Inverting input - accepts signals from 0 V to VDD; differential pair bias current <5 nA |
| 3 | IN+ A | Non-inverting input - same rail-to-rail CMVR as IN−; matched to IN− for low VIO |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling |
| 5 | IN+ B | Non-inverting input of second op-amp - electrically isolated from Channel A |
| 6 | IN− B | Inverting input of second op-amp - independent bias path; no crosstalk with Channel A |
| 7 | OUT B | Second amplifier output - identical AC/DC specs to OUT A; supports dual-sensor buffering |
| 8 | VDD+ | Positive supply - accepts 2.7–6 V; internal regulation ensures stable bias over voltage droop |

FAQ
What is the operating temperature range for TLV2452IDGKR?
The TLV2452IDGKR is rated for −40°C to +125°C free-air temperature operation, as indicated by the 'I' suffix in the part number. This industrial-grade specification is validated across all electrical parameters in the official TI datasheet SLOS218F, making TLV2452IDGKR suitable for deployment in automotive cabin modules, factory-floor sensors, and outdoor medical telemetry units where ambient extremes occur.
Does TLV2452IDGKR include a shutdown pin?
No, TLV2452IDGKR does not feature a shutdown pin. Per the TI TLV245x family datasheet, only TLV2450, TLV2453, and TLV2455 variants integrate shutdown functionality; TLV2452 uses an 8-pin MSOP (DGK) pinout with dedicated IN+/IN−/OUT/VDD/GND terminals for both channels and no SHDN terminal. The TLV2452IDGKR remains active whenever powered.
What package type is used for TLV2452IDGKR?
TLV2452IDGKR is packaged in 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 package is distinct from SOIC-8 (D) and TSSOP-8 variants, offering 40% smaller footprint than SOIC while maintaining manufacturability in standard SMT lines.
Can TLV2452IDGKR operate from a single 3 V supply?
Yes, TLV2452IDGKR is fully specified for single-supply operation from 2.7 V to 6 V, including 3 V. Datasheet sections confirm rail-to-rail input common-mode range (0 V to VDD) and output swing within 250 mV of each rail at 3 V with 2.5-mA load - enabling direct interfacing with 3 V microcontrollers and 12-bit+ ADCs without level-shifting circuitry.
What is the typical input offset voltage of TLV2452IDGKR?
The typical input offset voltage of TLV2452IDGKR is 20 µV at 25°C, as specified in the Electrical Characteristics table of the TI SLOS218F datasheet. Maximum VIO is 1300 µV across the full −40°C to 125°C temperature range, supporting precision applications such as thermopile amplification and bridge sensor conditioning where low initial error is essential.
