AD829ARZ

Overview

The AD829ARZ is a high-speed video operational amplifier manufactured by Analog Devices Inc., housed in an 8-lead SOIC package. It features a gain-bandwidth product of 750 MHz and a -3dB bandwidth of 600 MHz. The device delivers a slew rate of 150 V/µs with an input bias current of 7 µA and an input offset voltage of 1 mV. Operating on supply voltages between 9 V and 36 V, it maintains a power dissipation of 900 mW. Key performance metrics include a common-mode rejection ratio of 100 dB and a power supply rejection ratio of 98 dB. Input voltage noise density is specified at 1.7 nV/√Hz.

Feature Summary

• Custom compensation capability allows frequency response optimization for specific loads and supply voltages
• Designed to drive reverse-terminated 50 Ω or 75 Ω cables suitable for professional video applications
• Symmetrical input structure provides low input current noise characteristics

Applications

• Professional video signal processing circuits
• High-speed data acquisition systems requiring fast settling times
• Input buffering for analog-to-digital converters
• Current-to-voltage conversion stages for digital-to-analog converters

Procurement Notes

Verify the complete part number including suffixes against official Analog Devices documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets. Check for available evaluation boards such as the AD829AR-EBZ for circuit validation prior to implementation.

Selection Notes

Select this component when high bandwidth and low noise are critical for video or high-speed data applications. Consider the external compensation pins if gain settings require bandwidth adjustment. Ensure the operating temperature range meets system requirements given the wide specification limits. Verify that the supply voltage constraints align with the design power rails.

Part Context

This device belongs to the AD829 series of high-speed video amplifiers from Analog Devices. It is distinct from general-purpose op-amps due to its specialized compensation features and video-specific performance metrics. The family includes various package options, with the ARZ variant denoting the surface-mount SOIC configuration.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully before replacing existing designs.
