Overview
The AD9632ARZ is a high-speed, wide-bandwidth voltage feedback operational amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of ±3 V to ±5 V and consumes approximately 17 mA of quiescent current. The device features a small-signal bandwidth of 250 MHz and a large-signal bandwidth of 180 MHz at a gain of +2. Key performance metrics include a slew rate of 1300 V/µs, settling time of 16 ns to 0.01% for a 2 V step, and an input voltage noise density of 7.0 nV/√Hz. It is housed in an 8-lead SOIC package.
Feature Summary
- Voltage feedback architecture providing predictable operation and stability at gains of two or greater.
- Ultralow distortion characteristics with high third-order intercept point suitable for precision signal processing.
- High slew rate and fast settling time enabling accurate pulse response and transient handling.
- Wide bandwidth supporting both small-signal and large-signal frequency requirements.
Applications
- ADC input driver
- Differential amplifiers
- IF/RF amplifiers
- Pulse amplifiers
- Professional video
Procurement Notes
Verify the specific suffix 'RZ' indicates the RoHS-compliant SOIC-8 package variant when sourcing. Confirm that the application circuit maintains a closed-loop gain of +2 or higher to ensure stability, as this component is not unity-gain stable. Ensure power supply bypassing meets the datasheet recommendations to maintain specified performance levels.
Selection Notes
Select this component when a voltage feedback topology is required for stability in active filter designs or when driving ADCs with low distortion. It serves as a direct performance upgrade over previous generations like the AD9622. Consider the 8-lead SOIC footprint for PCB layout compatibility. Verify that the required gain does not fall below +2 to avoid oscillation risks associated with lower gain configurations.
Part Context
The AD9632ARZ belongs to the AD9631/AD9632 family of ultralow distortion, wide bandwidth voltage feedback op amps. While the AD9631 is unity-gain stable, the AD9632 variant is specifically designed for stability at gains of two or greater. This family bridges the gap between traditional voltage feedback predictability and the speed typically found in current feedback amplifiers.
Replacement Considerations
The AD9632AR is a non-RoHS equivalent offering identical electrical specifications. Designers transitioning from the AD9622 may find the AD9632 series provides improved performance metrics while maintaining similar functional roles in high-speed signal chains.
