HFA3-0005-5

Overview

The HFA3-0005-5 is a single-circuit, general-purpose operational amplifier manufactured by Harris Corporation. It is housed in an 8-pin PDIP package. Key electrical specifications include an input bias current of 15 µA and an output current capability of 50 mA per channel. The device operates across a supply voltage span of 12 V.

Feature Summary

• Single-circuit general-purpose operational amplifier design
• High output current capability for driving loads
• Standard 8-pin PDIP packaging for through-hole mounting

Applications

• General signal amplification circuits
• Buffer applications requiring moderate drive strength
• Instrumentation front-end stages

Procurement Notes

Verify the manufacturer part number against official Harris or Microchip documentation to ensure authenticity. Confirm that the 8-pin PDIP package matches your PCB footprint requirements. Check for specific suffix variations if available in official catalogs, as these may indicate temperature ranges or packaging differences. Ensure compliance with relevant industry standards for electronic components.

Selection Notes

Select this component when a single-channel op amp with 50 mA output drive is required. Consider the 15 µA input bias current for impedance matching in the application circuit. The 8-pin DIP form factor is suitable for prototyping or legacy board designs. Evaluate supply voltage constraints against the specified 12 V operating range before integration.

Part Context

This device belongs to the Harris HFA3 series of operational amplifiers. Harris Semiconductor was acquired by Intersil, which was subsequently acquired by Renesas Electronics. The product line represents older generation analog integrated circuits often used in industrial and consumer electronics applications where robustness and standard packaging are prioritized over ultra-low power consumption.

Replacement Considerations

Official substitute part numbers are not explicitly confirmed in the provided source material. Cross-reference with generic single-supply op amps offering similar 50 mA output current and 8-pin DIP packages if direct Harris/Microchip replacements are unavailable. Verify pin compatibility and electrical parameters before substitution.
