LTC6253CMS#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6253CMS#TRPBF is a dual, low-power, high-speed operational amplifier featuring unity-gain stability and rail-to-rail input/output capabilities. It operates within a supply voltage range of 2.5V to 5.25V with a typical quiescent current of 3.5mA per amplifier. Key electrical parameters include a gain-bandwidth product of 720MHz, a slew rate of 280V/µs, and an input-referred noise density of 2.75nV/√Hz. The device includes a shutdown pin that reduces supply current to 42µA when disabled. It is housed in an 8-lead MSOP package and is specified for operation from 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific temperature grade suffix (C, I, or H) matches the required operating environment, as performance specifications vary between commercial and industrial ranges. Confirm the MSOP-8 package type aligns with PCB layout constraints. Ensure the datasheet version corresponds to the manufacturing lot for accurate electrical characteristic validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high speed and low power consumption simultaneously. The dual configuration offers channel matching benefits over single amplifiers. Consider the shutdown feature if power management during idle states is critical. Verify that the load requirements do not exceed the output current limits at the intended supply voltage.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6252/LTC6253/LTC6254 family of rail-to-rail input/output op amps. The 'LTC6253' designation indicates a dual-channel configuration, distinguishing it from the single-channel LTC6252 and quad-channel LTC6254 variants. All members share identical electrical characteristics and pinouts where applicable.
