HA1-2655-5

Instrumentation, Op Amps, Buffer Amps Overview

The Harris Corporation HA1-2655-5 is a standard general-purpose operational amplifier featuring two independent circuits housed in a 14-pin CERDIP package. Designed for instrumentation and buffer applications, this dual op-amp offers a gain-bandwidth product of 80 kHz, an input bias current of 50 nA, and a voltage input offset of 2 mV. It operates with a supply current of 3 mA per circuit, providing reliable performance for general analog signal processing tasks requiring moderate precision and stability.

• General-purpose analog amplification

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation assets have been acquired by other entities such as Intersil or Renesas. Confirm the specific suffix '-5' denotes the correct temperature range or variant if critical. Ensure the 14-CERDIP package matches your PCB footprint requirements exactly. Check for original manufacturer markings to distinguish between new old stock and refurbished units.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution is required without the need for high-speed performance. The 80 kHz bandwidth limits suitability for high-frequency applications but supports low-power designs due to its 3 mA supply current. Consider the CERDIP package constraints for automated assembly processes compared to surface-mount alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the Harris HA1 series of linear integrated circuits, historically significant in the instrumentation amplifier market. The HA1-2655-5 represents a dual-channel variant within this family, sharing architectural similarities with other Harris op-amps while offering distinct pinout and performance characteristics tailored for general-purpose use cases.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes may include other dual general-purpose op-amps in DIP-14 packages such as the LM358 or TL082, though electrical parameters like offset voltage and bandwidth will differ. Verify pin compatibility and thermal specifications before substitution.
