AD9632ARZ-REEL

Overview

The AD9632ARZ-REEL is a wide bandwidth, ultralow distortion voltage feedback operational amplifier manufactured by Analog Devices Inc. It operates on ±3 V to ±5 V supplies with a quiescent current of 17 mA. The device features a small signal bandwidth of 250 MHz and a large signal bandwidth of 180 MHz at gains of +2 or greater. It provides a slew rate of 1300 V/µs and settles to 0.01% in 16 ns for a 2 V step. The component exhibits −113 dBc typical second harmonic distortion at 1 MHz and 7.0 nV/√Hz spectral noise density.

Feature Summary

• Voltage feedback architecture providing predictable operation and high phase margin
• Ultralow distortion performance suitable for demanding RF and IF applications
• High-speed transient response with fast settling time capabilities

Applications

• ADC input driver
• Differential amplifiers
• IF/RF amplifiers
• Pulse amplifiers
• Professional video

Procurement Notes

Verify the specific REEL suffix against the manufacturer's official ordering guide to confirm packaging specifications. Ensure the component meets industrial temperature range requirements (-40°C to +85°C) for your design environment. Cross-reference the datasheet revision history to confirm that electrical characteristics have not changed between manufacturing lots.

Selection Notes

Select this component when a gain of +2 or higher is required, as it is stable only at these levels unlike the unity-gain stable AD9631. Consider the voltage feedback topology if circuit predictability and active filter implementation are priorities over current feedback architectures. Evaluate power supply bypassing requirements to maintain optimal performance given the high-frequency nature of the device.

Part Context

This part belongs to the AD9631/AD9632 family of very high-speed amplifiers designed as improved alternatives to previous generations. While the AD9631 is unity gain stable, the AD9632 variant specifically targets applications requiring stability at gains of two or greater. Both share similar dynamic performance metrics but differ in their minimum stable gain configurations.

Replacement Considerations

The AD9631 serves as a functional alternative within the same family if unity gain stability is required instead of gain-of-two stability.
