HA3-2539-9

Instrumentation, Op Amps, Buffer Amps Overview

The HA3-2539-9 is a wideband operational amplifier manufactured by Harris Corporation. It features a voltage-feedback architecture with one functional circuit in a 14-pin ceramic DIP package. Key electrical parameters include a maximum input offset voltage of 15000 µV, a typical common-mode rejection ratio of 72 dB, and a minimum CMRR of 60 dB. The device operates within a temperature range of -55°C to +125°C for military specifications or 0°C to +75°C for commercial variants. It requires frequency compensation when the closed-loop gain is greater than or equal to 10.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix variant (e.g., -9 vs -5) against the required temperature range and packaging type. Confirm RoHS compliance status as older Harris components may not meet current environmental standards. Ensure the supplier provides traceable documentation for military-grade parts if operating in harsh environments. Check lead times due to potential obsolescence or limited production runs for legacy Harris products.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring wide bandwidth and low offset voltage in a robust ceramic package. Consider the 15000 µV max offset voltage for precision requirements. Evaluate the need for external frequency compensation based on the target closed-loop gain. Compare thermal performance between commercial and military temperature ranges to ensure suitability for the intended operating environment.
