AD812ARZ-REEL

Overview

The AD812ARZ-REEL is a dual-channel, low-power video amplifier manufactured by Analog Devices Inc. It utilizes current feedback architecture to deliver high-speed performance in a compact SOIC-8 surface-mount package. The device operates on a single +3 V to +36 V supply or dual ±1.2 V to ±18 V supplies, drawing 4.5 mA per channel at +5 V. Key electrical parameters include a 145 MHz gain-bandwidth product and a 1600 V/µs slew rate. It provides 50 mA output current capability, supporting 150 Ω terminated video loads with minimal distortion.

Feature Summary

• Dual-channel current feedback topology optimized for professional video applications
• High slew rate and bandwidth suitable for driving terminated video loads
• Low power consumption enabling operation from single +5 V sources
• Minimal differential gain and phase errors ensuring signal integrity

Applications

• Video line drivers
• Camera systems
• Video switchers

Procurement Notes

Verify the specific REEL suffix against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the component matches the required SOIC-8 footprint and lead-free RoHS compliance standards. Cross-reference the part number with authorized distributors to confirm availability status and authenticity before procurement.

Selection Notes

Select this component when designing circuits requiring dual independent video amplification with high speed and low power constraints. The current feedback design offers superior transient response compared to voltage feedback alternatives. Ensure the application supports the specified operating temperature range of -40°C to +85°C and utilizes appropriate decoupling for the wide supply voltage range.

Part Context

This part belongs to the AD812 series of low-power video amplifiers. It is the reel-packaged variant of the standard AD812ARZ, designed for automated surface-mount assembly processes. The series is characterized by its ability to drive 75 Ω or 150 Ω video loads directly without external buffering components.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the same family. Verify that any alternative maintains the 145 MHz bandwidth and 50 mA output current requirements.
