ADA4859-3ACPZ-R2

Overview

The ADA4859-3ACPZ-R2 is a triple, single-supply, high-speed video amplifier with an integrated charge pump. It operates on a supply voltage range of 3 V to 5.5 V and provides a fixed gain of +2. The device features a -3 dB bandwidth of 195 MHz at 2 V p-p output and a slew rate of 740 V/µs. Total quiescent current is 38 mA. The package is a 16-lead LFCSP.

Feature Summary

• Integrated charge pump generates negative supply for single-supply operation
• Fixed internal gain of +2 eliminates external feedback resistors
• Power-down pin reduces total supply current significantly when inactive
• High input common-mode voltage range extending below ground

Applications

• Professional video signal processing
• Consumer video applications
• Imaging systems
• Active filters

Procurement Notes

Verify the specific ordering suffix R2 corresponds to the 250-unit reel quantity as listed in the official Analog Devices ordering guide. Confirm RoHS compliance status via the manufacturer's documentation before procurement. Ensure the exposed pad connection requirements are met during assembly.

Selection Notes

Select this component for applications requiring a fixed gain of +2 without external resistors. It is suitable for designs needing a negative rail generated from a single positive supply. Consider the power-down feature for low-power standby modes. Verify that the 16-lead LFCSP package fits the PCB layout constraints.

Part Context

This part belongs to the ADA4859-3 series of triple video amplifiers. It is designed by Analog Devices Inc. for high-speed video applications. The device simplifies design by integrating gain-setting resistors and a charge pump. It is available in industrial temperature ranges.

Replacement Considerations

ADA4859-3ACPZ-R7 and ADA4859-3ACPZ-RL are alternative packaging options within the same family.
