Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' corresponds to the extended industrial temperature range (-40°C to +125°C) as defined in the datasheet. Confirm the 'T' indicates tape and reel packaging. Ensure the MSOP-8 footprint matches the PCB layout requirements. Cross-reference the manufacturer part number against official Microchip documentation to validate authenticity and revision status before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption is critical alongside high DC accuracy. The 2 MHz bandwidth supports moderate-speed signal processing. Consider the 170 µA quiescent current for battery-operated designs. Verify that the 2V to 5.5V supply range aligns with system power constraints. The dual configuration allows cost-effective implementation of multi-channel signal paths.
