Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'AD' indicates the SOIC-8 non-reel packaging format as per the ordering information table. Confirm that the device status is reviewed against the discontinuation notice dated July 31, 2025, which lists MC33272AD as discontinued. Ensure compatibility with required industrial temperature ranges if operating outside standard limits.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low input offset voltage and high slew rate are critical for signal integrity. The dual-channel configuration supports applications requiring two independent amplifiers in a compact SOIC-8 footprint. Consider the 24 MHz gain bandwidth product for wideband signal conditioning tasks where phase margin stability under capacitive loads is required.

Instrumentation, Op Amps, Buffer Amps Part Context

The MC33272AD belongs to the MC33272/74 series of monolithic operational amplifiers. This family is characterized by innovative Bipolar design concepts and Zip-R-Trim technology.
