Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments, as the brand history involves acquisition. Confirm the package type is 8-SOIC and the temperature range covers industrial levels. Ensure the datasheet specifies the shutdown pin functionality if power management is required for the specific design implementation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and low voltage operation are critical. The CMOS technology provides speed advantages over bipolar counterparts while maintaining low power draw. Consider the shutdown feature for systems requiring extended battery life. Verify input common-mode range requirements against the rail-to-rail specification.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx355 series of high-speed CMOS amplifiers. It shares architectural similarities with the OPA356 but includes additional shutdown functionality. The series targets applications demanding fast settling times and wide bandwidth in compact packages. It represents a transition point in Burr-Brown's portfolio before full integration into Texas Instruments' lineup.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA356 serves as a related variant within the same family, lacking the shutdown feature. Check for availability of the OPA355NA variant for different packaging options. Verify pin compatibility if substituting with other high-speed CMOS op-amps from the manufacturer.
