HA7-2645-7

Instrumentation, Op Amps, Buffer Amps Overview

The HA7-2645-7 is a general-purpose operational amplifier manufactured by Harris Corporation. It features a single circuit configuration housed in an 8-CERDIP package with a 0.300-inch (7.62mm) width. The device operates within a supply voltage span ranging from a minimum of 20 V to a maximum of 80 V. Key electrical specifications include a gain bandwidth product of 4 MHz and a slew rate of 5V/µs. This component is designed for through-hole mounting applications requiring robust linear amplification capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets have been acquired by other entities such as Intersil or Renesas. Confirm the specific suffix indicates the correct temperature range and packaging variant. Ensure the component meets current RoHS compliance requirements if applicable to your project standards. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high supply voltage tolerance is required alongside moderate bandwidth performance. The 4 MHz gain-bandwidth product suits applications where speed is secondary to voltage handling capacity. Consider the 8-CERDIP package constraints for PCB layout and thermal management. Evaluate the 5V/µs slew rate against signal frequency requirements to ensure minimal distortion in the target application environment.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the Harris Corporation line of standard operational amplifiers. These devices were widely used in industrial and military electronics before corporate restructuring. The HA7 series represents a legacy component line now managed by successor companies holding the intellectual property rights.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with modern equivalents from Intersil or Renesas, which hold the Harris semiconductor assets. Check pinout and electrical parameter alignment before substitution.
