AD9631ARZ-REEL

Overview

The AD9631ARZ-REEL7 is a high-speed, wide-bandwidth 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. Key electrical parameters include a small-signal bandwidth of 320 MHz and a large-signal bandwidth of 175 MHz at a gain of +1. The device features a slew rate of 1300 V/µs and settles to 0.01% in 16 ns for a 2 V step. It offers ultralow distortion with an SFDR of −113 dBc at 1 MHz and a spectral noise density of 7.0 nV/√Hz. The component is housed in an 8-lead SOIC package.

Feature Summary

Unity gain stable voltage feedback architecture providing predictable design characteristics.

Applications

ADC input driver
Differential amplifiers
IF/RF amplifiers

Procurement Notes

Verify the specific ordering suffix REEL7 against the manufacturer's official documentation to confirm packaging details. Ensure the component grade matches the required industrial temperature range specifications. Cross-reference the datasheet revision history to confirm that all performance parameters align with the latest published standards before finalizing procurement decisions.

Selection Notes

Select this component when a unity gain stable configuration is required alongside high-speed transient response. The voltage feedback structure allows for flexible active filter designs not possible with current feedback alternatives. Consider the specific feedback resistor values recommended in the datasheet to optimize bandwidth and stability for the target application frequency.

Part Context

This part belongs to the AD9631/AD9632 series of ultralow distortion, wide bandwidth voltage feedback op amps. It serves as an improved performance alternative to previous generations like the AD9621. The AD9631 variant is specifically designed for unity gain stability, distinguishing it from the AD9632 which requires gains of two or greater.
