AD829JRZ-REEL7

Overview

The AD829JRZ-REEL7 is a high-speed video operational amplifier manufactured by Analog Devices Inc. It features a single voltage feedback architecture housed in an 8-SOIC surface-mount package. Key electrical specifications include a gain-bandwidth product of 750 MHz, a -3dB bandwidth of 120 MHz at a gain of -1, and a slew rate of 230 V/µs. The device operates on dual supply voltages ranging from ±4.5V to ±18V with a typical supply current of 5.3 mA. It exhibits low input voltage noise density of 1.7 nV/√Hz and supports output currents up to 32 mA.

Feature Summary

• Customizable frequency response via external compensation pins for optimized performance across various gains
• Low noise characteristics suitable for professional video signal processing applications
• Capable of driving reverse-terminated 50 Ω or 75 Ω cables effectively

Applications

• Professional video amplification and signal conditioning
• High-speed data acquisition systems
• Buffering for analog-to-digital converters

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the 8-SOIC physical footprint. Check datasheet revisions for any updates to electrical limits or thermal characteristics before final integration.

Selection Notes

Select this component for applications requiring high slew rates and wide bandwidth in a compact surface-mount form factor. Consider the external compensation capability if gain stability adjustments are needed. Verify that the power supply range aligns with the ±4.5V to ±18V specification and that the thermal dissipation capabilities of the SOIC package suit the design environment.

Part Context

This part belongs to the AD829 series of high-speed video amplifiers from Analog Devices. The series is designed for demanding video and RF applications where signal integrity and speed are critical. The JRZ variant specifically denotes the industrial temperature range and the SOIC package style, while the REEL7 suffix specifies the bulk packaging method for automated assembly.

Replacement Considerations

Consult official Analog Devices documentation for direct pin-compatible substitutes within the AD829 family. Verify that any alternative maintains the required 750 MHz gain-bandwidth product and 230 V/µs slew rate. Ensure the replacement package matches the 8-SOIC dimensions for board compatibility.
