AD829JRZ

Overview

The AD829JRZ is a high-speed video operational amplifier manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It features a gain-bandwidth product of 750 MHz and a -3dB bandwidth of 600 MHz, with a slew rate of 150 V/µs. The device operates on supply voltages ranging from 9 V to 36 V and draws 5.3 mA of supply current. Key electrical specifications include an input bias current of 7 µA, an input offset voltage of 1 mV, and an input voltage noise density of 1.7 nV/√Hz. It offers a common-mode rejection ratio of 100 dB and a power supply rejection ratio of 98 dB, functioning as a general-purpose amplifier within the AD829 series.

Feature Summary

• Features external compensation pins allowing users to adjust frequency response for specific load and supply conditions.
• Capable of driving reverse-terminated 50 Ω or 75 Ω cables suitable for professional video applications.
• Provides symmetric inputs with low input current noise of 1.5 pA/√Hz.

Applications

• Professional video signal processing
• High-speed data acquisition systems
• Input buffering for analog-to-digital converters

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type, as variations exist between tube and reel formats. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the operating temperature range meets system requirements, as industrial variants may differ. Cross-reference the full part number with Analog Devices to validate availability and revision history before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high bandwidth and fast settling times for video or data conversion applications. Consider the external compensation capability if optimizing performance for specific gain settings or loads. Evaluate the 8-SOIC package constraints against board space requirements. Compare the 150 V/µs slew rate against application needs to ensure adequate signal fidelity without distortion.

Part Context

The AD829JRZ belongs to the AD829 family of low-noise, high-speed operational amplifiers designed for demanding signal processing tasks. This series is characterized by its ability to maintain high bandwidth across various gain configurations through user-adjustable compensation. The JRZ designation specifically identifies the SOIC-8 surface-mount variant within the broader AD829 product line offered by Analog Devices.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Do not assume pin compatibility or electrical equivalence with other video amplifiers without explicit manufacturer confirmation.
