AD812AR-REEL

Overview

The AD812AR-REEL7 is a dual, low-power, current feedback video amplifier manufactured by Analog Devices Inc. It operates on single supplies from +3 V to +5 V or dual supplies up to ±15 V. Key electrical parameters include a unity gain bandwidth of 145 MHz and a slew rate of 1600 V/ms at ±15 V. The device provides 50 mA output current per amplifier and features excellent video specifications such as 0.02% differential gain error and 0.028° differential phase error into a 150 Ω load. It is housed in an 8-lead SOIC package.

Feature Summary

• Dual current feedback architecture optimized for driving back-terminated video loads with high gain flatness.
• Low power consumption allowing operation on a single +3 V supply while maintaining high-speed performance.
• Internal short-circuit protection and fast overload recovery times for robust signal handling.
• Rail-to-rail output swing capability accommodating standard video signal amplitudes.

Applications

• Video line drivers
• Professional cameras
• Video switchers

Procurement Notes

Verify the specific ordering suffix (REEL vs REEL7) against the manufacturer's official documentation to ensure correct packaging quantity. Confirm that the component matches the industrial temperature range requirements (-40 °C to +85 °C). Ensure ESD precautions are observed during handling due to the sensitivity of the internal circuitry.

Selection Notes

Select this component for applications requiring dual amplification in a compact form factor with minimal power dissipation. The current feedback topology is suitable for wideband video signals where gain bandwidth product stability is critical. Consider the 150 Ω load optimization when designing for professional video standards.

Part Context

This part belongs to the AD812 family of dual video amplifiers. It is designed to replace older discrete solutions or single-channel amplifiers in portable and battery-powered video equipment. The device utilizes a complementary bipolar process to achieve high speed and low noise within a small 8-lead plastic package.

Replacement Considerations

Check for AD812AN or AD812AR variants if different packaging options are required. Verify pinout compatibility before substituting with other dual video amplifiers.
