Product Introduction

Overview

The AD812ARZ, produced by Analog Devices Inc., is a low power, single supply, dual video amplifier. This component is designed to optimize performance in video systems, particularly for driving back-terminated video loads. Each amplifier in the AD812ARZ has an output current of 50 mA and is housed in an 8-lead SOIC package, making it suitable for both portable and battery-powered applications due to its compact size and low power consumption.

  • Low power operation with a single +3 V to +36 V supply or dual ±1.2 V to ±18 V supply.
  • High speed performance with a 145 MHz unity gain bandwidth and 1600 V/μs slew rate.
  • Excellent video specifications: 0.1 dB gain flatness to 40 MHz, 0.02% differential gain error, and 0.02° differential phase error.
  • Output current of 50 mA per channel and output swing to within 1 V of either supply rail.
  • Low quiescent current of 3.0 mA to 4.0 mA per amplifier.
  • Industrial temperature range of -40°C to +85°C.

Applications

  • Video line drivers in professional video systems.
  • Professional cameras and video switchers.
  • Special effects equipment in video production.
  • General-purpose high-speed applications requiring single or dual power supplies.
  • Portable and battery-powered applications due to low power consumption and compact size.
