AD813ARZ-14

Overview

The AD813ARZ-14 is a low-power, single-supply, triple-channel video amplifier manufactured by Analog Devices Inc. It utilizes a current-feedback architecture to deliver high-speed performance suitable for professional video applications. The device features a unity-gain bandwidth of 125 MHz and a slew rate of 500 V/µs. Each channel provides 50 mA output current, optimized for driving 150 Ω back-terminated video loads. Key video specifications include 0.1 dB gain flatness at 50 MHz, with differential gain and phase errors of 0.03% and 0.06°, respectively. It operates on supply voltages ranging from +3 V single supply to ±15 V dual supply.

Feature Summary

• Integrates three independent current-feedback amplifiers in a single package for compact system design.
• Optimized for video cable driving with excellent gain flatness and minimal differential gain/phase errors.
• Features high-speed disable functionality allowing entry into power-saving mode or high-impedance state.
• Supports wide supply voltage ranges including single +3 V operation for battery-powered portability.

Applications

• Broadcast equipment signal processing
• Consumer video electronics
• Portable display drivers

Procurement Notes

Verify the specific suffix -14 against official Analog Devices documentation to confirm pinout and package configuration. Confirm RoHS compliance status through the manufacturer's datasheet. Check availability as distribution may vary. Ensure the selected variant matches the required industrial temperature range and packaging type for the target application.

Selection Notes

Select this component when multiple video channels are required within a limited board area. The current-feedback topology offers superior slew rate compared to voltage-feedback alternatives. Consider the 50 mA drive capability for direct loading of standard video impedances without additional buffering stages. Evaluate power consumption constraints given the low quiescent current per channel.

Part Context

This part belongs to the AD813 series of video amplifiers designed for analog video signal conditioning. It serves as a bridge between legacy video standards and modern low-voltage digital systems. The triple-channel configuration reduces component count in multi-line video interfaces. It is distinct from the AD8131 and AD8132 differential driver families which serve different signal conversion roles.
