LTC6253HMS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The Analog Devices LTC6253HMS8#PBF is a dual, low-power, high-speed operational amplifier featuring rail-to-rail input and output capabilities. It operates on supply voltages ranging from 2.5V to 5.25V with a typical quiescent current of 3.5mA per amplifier. Key electrical specifications include a gain-bandwidth product of 720MHz, a slew rate of 280V/µs, and an input-referred voltage noise density of 2.75nV/√Hz. The device includes a shutdown pin that reduces current consumption to 42µA when disabled. It is housed in an 8-lead MSOP package and is specified for operation over the -40°C to 125°C temperature range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix H indicates the extended temperature grade (-40°C to 125°C) compared to standard industrial grades. Confirm the MSOP-8 package dimensions match your PCB footprint requirements. Ensure the datasheet revision matches your design specifications. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high speed and low power are critical constraints. The dual configuration offers better channel matching than single amplifiers. Consider the shutdown feature if system power management requires disabling unused channels. Verify that the required load capacitance does not exceed stability limits without series isolation resistors. Compare against the single-channel LTC6252 or quad-channel LTC6254 based on channel count needs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6252/LTC6253/LTC6254 family of unity-gain stable op amps. The 'LTC6253' designation identifies it as the dual-channel variant within this series. The 'H' suffix denotes the extended industrial temperature range, while 'MS8' specifies the 8-lead Mini-SOP package. This family is designed to replace older, higher-power rail-to-rail op amps in existing designs.
