Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin, as Texas Instruments has acquired Harris Semiconductor assets. Confirm the specific suffix 'A-5' matches the required pinout and specification variant. Ensure the package type corresponds to the legacy Harris designation rather than modern equivalents. Cross-reference datasheets for any parameter shifts due to manufacturing transitions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high slew rate and low offset drift are critical. It is suitable for applications demanding 80 MHz bandwidth alongside microvolt-level precision. Consider the 8-pin DIP form factor for through-hole compatibility. Evaluate if the 10 nA bias current meets the source impedance requirements of the circuit design.
