TLV2453IDR

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2453IDR is a dual micropower rail-to-rail input/output operational amplifier featuring an ultralow-power shutdown mode. It operates on a single supply voltage ranging from 2.7 V to 6 V, or split supplies of ±1.35 V to ±3 V. The device consumes 23 µA per channel in active mode and drops to 16 nA per channel during shutdown. Key electrical parameters include a gain-bandwidth product of 220 kHz, a slew rate of 0.11 V/µs, and an output drive capability of ±10 mA. It supports an industrial temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capabilities maximize dynamic range in low-voltage applications.
• Ultralow-power shutdown mode conserves battery life by placing outputs in a high-impedance state.
• High output drive capability solves limitations found in older micropower amplifiers.

Instrumentation, Op Amps, Buffer Amps Applications

• Portable medical equipment
• Patient monitoring systems
• Data acquisition circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the 'I' suffix indicates the extended industrial temperature range (-40°C to +125°C) rather than commercial grade. Confirm the 'DR' suffix specifies tape-and-reel packaging for automated assembly. Ensure the datasheet revision matches the design requirements, as specifications may vary between revisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both rail-to-rail signal handling and minimal power consumption are required. The shutdown feature makes it suitable for battery-operated devices where standby current must be minimized. Compare against the TLV246x series if higher bandwidth is needed, or the TLV245xA variants for tighter offset voltage specifications.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLV245x family of operational amplifiers designed for micropower applications. The family includes single (TLV2450/1), dual (TLV2452/3), and quad (TLV2454/5) configurations. All members share similar electrical characteristics but differ in channel count and package options.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the shutdown mode activated?

The shutdown mode is activated by driving the SHDN pin to a logic low level relative to the GND terminal.

What is the maximum supply voltage?

The absolute maximum supply voltage is 7 V, but the recommended operating range is up to 6 V.
