HA1-2539C-9

Instrumentation, Op Amps, Buffer Amps Overview

The HA1-2539C-9 is a single operational amplifier manufactured by Harris Corporation. It utilizes a voltage-feedback architecture and is housed in a 14-pin ceramic dual in-line package (CDIP). The device operates within a temperature range of -40°C to 85°C and supports supply voltages up to ±18 V, with a nominal rating of ±15 V. Key electrical specifications include a maximum input offset voltage of 15 mV, a maximum bias current of 20 µA at 25°C, and a minimum common-mode rejection ratio of 60 dB.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Voltage-feedback operational amplifier architecture
• Metal-sealed ceramic DIP-14 packaging
• Internal frequency compensation for closed-loop gains of 10 or greater

Instrumentation, Op Amps, Buffer Amps Applications

• Precision analog signal processing circuits
• Industrial instrumentation systems
• Military-grade electronic equipment

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'C' against official Harris datasheets to confirm it denotes the commercial temperature grade (-40°C to 85°C) rather than a different variant. Confirm RoHS compliance status, as historical Harris bipolar op-amps often lack modern environmental certifications. Validate that the CDIP-14 package matches the required footprint for the target application.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a high-voltage bipolar operational amplifier with moderate precision is required. The 15 mV offset voltage limits suitability for ultra-low drift applications. Ensure the design accommodates the 20 µA bias current and the requirement for external frequency compensation only if gain is below 10. Verify power supply rails do not exceed the ±18 V absolute maximum rating.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the Harris HA1 series of bipolar operational amplifiers. These devices were designed for robust performance in demanding environments. The manufacturer, Harris Corporation, has undergone corporate restructuring, with its semiconductor assets largely acquired by Intersil and subsequently Renesas Electronics.
