Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the authenticity of the manufacturer documentation directly from Harris Corporation archives or authorized heritage distributors. Ensure the specific lot code matches military procurement standards. Confirm that the CDIP package dimensions align with existing board layouts, as modern surface-mount alternatives may require adapter solutions. Check for RoHS compliance status if integrating into non-military commercial assemblies.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when hermetic sealing is mandatory for long-term reliability in extreme temperatures or vacuum conditions. Compare against modern JFET-input op-amps if lower input bias current is required, noting potential differences in bandwidth. Evaluate power consumption constraints against the bipolar supply requirements. Consider pin-out compatibility with legacy designs to avoid redesigning support circuitry.

Instrumentation, Op Amps, Buffer Amps Part Context

The HA7 series represents a lineage of precision operational amplifiers developed by Harris Semiconductor, later acquired by Intersil and subsequently Renesas Electronics. The /883 suffix denotes compliance with MIL-STD-883 testing procedures for microelectronics. These devices were widely used in military avionics during the late 20th century. The HA7-2602 specifically targets dual-channel applications needing high slew rate and wide bandwidth without sacrificing DC precision.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Official direct replacements are scarce due to the discontinuation of the original Harris manufacturing line. Potential substitutes include other hermetically sealed dual op-amps from manufacturers like Analog Devices or Texas Instruments that offer MIL-STD-883 certification. Verify electrical parameter equivalence, particularly offset voltage and bandwidth, before substituting. Mechanical footprint compatibility must be confirmed for DIP14 packages.

Instrumentation, Op Amps, Buffer Amps FAQ

What does the /883 suffix indicate for the HA7-2602?

The /883 suffix indicates that the device has been tested and qualified according to MIL-STD-883, the standard test methods and procedures for microelectronics, ensuring suitability for military and aerospace applications.

Is the HA7-2602 available in a surface-mount package?

No, the HA7-2602 is typically supplied in a hermetically sealed Ceramic Dual In-Line Package (CDIP). Surface-mount equivalents would require different part numbers from modern manufacturers.

Can the HA7-2602 operate with single-supply voltages?

While primarily designed for dual bipolar supplies, operation with single supplies may be possible if the common-mode input voltage range and output swing specifications allow it within the specific application constraints.
