AD9632AN

Overview

The AD9632AN is a high-speed, wide-bandwidth voltage feedback operational amplifier manufactured by Analog Devices Inc. It is stable at gains of 2 or greater and serves as an improved replacement for the AD9622. The device features a small signal bandwidth of 250 MHz and a large signal bandwidth of 180 MHz (4 V p-p). Key electrical parameters include a slew rate of 1500 V/μs, a settling time of 16 ns to 0.01% for a 2 V step, and a typical third-order intercept point of 41 dBm at 25 MHz. It operates on dual supplies ranging from ±3 V to ±6 V with a quiescent current of approximately 17 mA.

Feature Summary

• Voltage feedback architecture providing stability at gains of 2 or greater.
• Ultralow distortion characteristics suitable for high-fidelity signal processing.
• High slew rate and fast settling time for precise pulse response.
• Balanced high-impedance inputs offering flexibility in active filter design.

Applications

• ADC input driver
• Differential amplifiers
• IF/RF amplifiers
• Active filters

Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's current ordering guide to confirm package type and temperature grade availability. Ensure the procurement channel provides valid traceability documentation. Confirm that the component matches the exact datasheet revision required for your circuit design specifications before finalizing orders.

Selection Notes

Select the AD9632AN when a gain of 2 or higher is required, as it is optimized for this configuration unlike the unity-gain stable AD9631. Consider its voltage feedback structure if predictable phase margin and classic op-amp behavior are preferred over current feedback architectures. Evaluate the 250 MHz bandwidth against system requirements to ensure adequate headroom for signal fidelity.

Part Context

The AD9632 is part of the AD9631/AD9632 family of ultralow distortion, wide bandwidth voltage feedback op amps. It is positioned as a performance-enhanced successor to the AD9622. While the AD9631 is designed for unity gain stability, the AD9632 variant is specifically characterized for stability at non-inverting gains of 2 or greater, sharing similar dynamic performance metrics within the series.

Replacement Considerations

The AD9632 is documented as a direct performance improvement replacement for the AD9622. Verify pin compatibility and thermal characteristics when transitioning from legacy parts. No other substitute part numbers are confirmed in the provided source material.
