Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Harris Corporation to ensure authenticity. Confirm the TO-99-8 package style matches system requirements. Check RoHS compliance status if environmental regulations apply. Ensure the part number suffix 'AT' corresponds to the specific temperature or grade variant required for your application. Validate datasheet parameters against current design constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual op-amp solution is needed in a hermetic metal package. Consider the 1 MHz gain bandwidth product for moderate-speed applications. Evaluate the 20 nA input bias current for high-impedance source interfacing. Compare the 700 µA supply current against power budget constraints. Ensure compatibility with existing TO-99 footprints and mounting methods.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the CA158 family of dual operational amplifiers from Harris Corporation. The CA158 series is characterized by its use in commercial, industrial, and military sectors. The CA0158AT represents a specific variant within this lineage, maintaining the core dual-amplifier architecture while potentially differing in testing or qualification standards associated with the 'AT' suffix.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes may include other dual op-amps in TO-99 packages with similar 1 MHz bandwidth and low bias current characteristics. Verify pinout compatibility before substitution. Cross-reference with Harris/Littelfuse official replacement guides for qualified alternatives.
