ADA4856-3YCPZ-R7

Overview

The ADA4856-3YCPZ-R7 is a triple, single-supply, high-speed video amplifier with a fixed internal gain of +2. It features rail-to-rail output capability and operates on supply voltages ranging from 3 V to 5.5 V. Key performance metrics include a -3 dB bandwidth of 225 MHz at 2 V p-p, a slew rate of 800 V/μs, and a settling time of 5 ns to 0.1%. The device draws a typical quiescent current of 7.8 mA per amplifier and includes a power-down function that reduces current consumption to approximately 1 mA. It is housed in a 16-lead LFCSP package.

Feature Summary

• Voltage feedback architecture with fixed internal gain of +2
• Rail-to-rail output swing extending within 0.1 V of supply rails
• Integrated power-down feature for low-power operation
• High input common-mode voltage range extending below ground

Applications

• Professional video systems
• Consumer video equipment
• Imaging applications
• Instrumentation circuits
• Base station signal processing

Procurement Notes

Verify the specific ordering suffix YRUZ or YCPZ against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Cross-reference the pinout diagram with your PCB layout to ensure compatibility with the 16-lead LFCSP footprint.

Selection Notes

Select this component when a fixed gain of +2 is required for video signal conditioning. It is suitable for single-supply designs operating between 3 V and 5.5 V. Consider the power-down pin if energy efficiency during idle states is critical. Verify that the 225 MHz bandwidth and 800 V/μs slew rate meet the dynamic requirements of the target application.

Part Context

This part belongs to Analog Devices' line of single-supply video amplifiers designed for high-speed signal processing. The ADA4856-3 integrates three identical amplifiers into one package, reducing board space compared to discrete solutions. It utilizes an XFCB3 process to achieve high speed and low noise. The fixed gain design eliminates external feedback resistors, simplifying circuit layout and improving matching consistency.

Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as the ADA4856-1 (single) or ADA4856-2 (dual), if channel count differs. Verify electrical parameters like bandwidth and slew rate against alternative triple video amplifiers from other manufacturers if sourcing constraints exist.
