AD812ARZ-REEL7

Overview

The AD812ARZ-REEL7 is a dual, low-power, current-feedback video amplifier manufactured by Analog Devices Inc. It features a gain-bandwidth product of 145 MHz and a slew rate of 1600 V/µs, enabling high-speed signal processing. Each channel delivers an output current of 50 mA, suitable for driving 150 Ω terminated video loads. The device operates on a single supply from +3 V to +36 V or dual supplies up to ±18 V, with a typical quiescent current of 4.5 mA per channel at +5 V. It exhibits low differential gain (0.02%) and phase (0.02°) errors, ensuring high-fidelity video transmission.

Feature Summary

• Current-feedback architecture provides wide bandwidth independent of noise gain.
• High output drive capability supports direct termination of standard video loads.
• Low differential gain and phase errors preserve video signal integrity.
• Single-supply operation simplifies power design in portable applications.

Applications

• Professional video equipment line drivers
• Video switching matrices
• Camera signal conditioning
• Special effects generators

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range meets system requirements. Check for any lead-free certification details relevant to your assembly process. Validate pinout compatibility if replacing existing components.

Selection Notes

Select this component for applications requiring high slew rates and wide bandwidth in a dual-channel configuration. The current-feedback topology is advantageous for maintaining stability across varying gains. Consider the 50 mA output current for driving heavy capacitive or resistive loads without external buffering. Evaluate power consumption against battery life requirements for portable designs.

Part Context

The AD812 series belongs to Analog Devices' portfolio of high-speed video amplifiers. The ARZ variant denotes a lead-free, RoHS-compliant version in an SOIC-8 package. This family is designed for professional video and general-purpose high-speed analog applications where signal fidelity and speed are critical.

Replacement Considerations

Direct replacements include other AD812 variants such as AD812AR or AD812AN, depending on package preference. Verify that substitute parts maintain the same current-feedback architecture and electrical specifications to ensure circuit compatibility.
