AD9632AR-REEL

Overview

The AD9632AR-REEL is a wide bandwidth, ultralow distortion voltage feedback operational amplifier manufactured by Analog Devices Inc. It operates with ±3 V to ±5 V supplies and draws 17 mA of quiescent current. The device features a small signal bandwidth of 250 MHz and a large signal bandwidth of 180 MHz at 4 V p-p. It provides a slew rate of 1300 V/µs and settles to 0.01% in 16 ns for a 2 V step. The unit is housed in an 8-lead SOIC package and is stable at gains of +2 or greater.

Feature Summary

• Voltage feedback architecture providing predictable operation and high phase margin
• Ultralow harmonic distortion and low spectral noise density
• High-speed pulse response with fast settling time capabilities
• Balanced high impedance inputs suitable for active filter designs

Applications

• ADC input driver
• Differential amplifiers
• IF/RF amplifiers
• Pulse amplifiers
• DAC current to voltage conversion

Procurement Notes

Verify the specific ordering suffix AR-REEL against the manufacturer's official documentation to confirm the reel packaging format and tape specifications. Ensure the component grade matches the required industrial temperature range of -40°C to +85°C. Cross-reference the datasheet revision to confirm electrical characteristics remain unchanged from previous versions.

Selection Notes

Select this component when a voltage feedback topology is preferred over current feedback for better stability in complex filter networks. The AD9632 requires a minimum closed-loop gain of +2 for stability; verify circuit requirements align with this constraint. Consider the 250 MHz bandwidth and 1300 V/µs slew rate for high-frequency signal processing applications requiring low distortion.

Part Context

The AD9632 is part of the AD9631/AD9632 family of very high-speed amplifiers designed as improved alternatives to earlier models like the AD9621. While the AD9631 is unity gain stable, the AD9632 variant is specifically optimized for stability at gains of two or greater. Both devices share similar dynamic performance metrics but differ in their recommended operating configurations.

Replacement Considerations

The AD9631 serves as a related family member but differs in stability requirements, being unity gain stable unlike the AD9632.
