AD829JR-REEL7

Overview

The AD829JR-REEL7 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 ±4.5V to ±18V (single/dual) or up to 36V maximum, drawing approximately 5.3 mA of supply current. Key electrical characteristics include an input offset voltage of 1 mV, input bias current of 7 µA, and low input voltage noise density of 1.7 nV/√Hz. It provides a common-mode rejection ratio of 100 dB and power supply rejection ratio of 98 dB.

Feature Summary

• High-speed voltage feedback architecture optimized for professional video applications
• Low input voltage noise density of 1.7 nV/√Hz for signal integrity
• External compensation capability allows frequency response adjustment across gains of 1 to 20
• Capable of driving reverse-terminated 50Ω or 75Ω cables with minimal differential gain and phase errors

Applications

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

Procurement Notes

Verify the specific suffix 'JR' against official Analog Devices documentation to confirm temperature range and packaging specifications. Ensure the reel quantity matches production requirements. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status before procurement.

Selection Notes

Select this component when high bandwidth and low noise are critical for video or fast transient signals. Consider the external compensation pin if gain stability adjustments are needed. Verify that the 8-SOIC package fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the AD829 series of high-speed video amplifiers from Analog Devices. The series is designed for applications requiring precise signal handling at high frequencies. The JR variant typically denotes a specific commercial temperature range and tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

Consult Analog Devices datasheets for direct replacements within the AD829 family. Verify pin compatibility and electrical parameter equivalence for any substitute components.
