ADA4855-3YCPZ-R2

Overview

The ADA4855-3YCPZ-R2 is a single-supply, high-speed, rail-to-rail output triple operational amplifier. It features a voltage feedback architecture with a 410 MHz bandwidth at unity gain and an 870 V/µs slew rate. The device operates on a supply range of 3 V to 5.5 V, drawing 7.8 mA per amplifier. It includes a power-down function reducing current to approximately 1 mA. The input common-mode range extends from the negative rail minus 0.2 V to the positive rail minus 1 V. It is housed in a 16-lead LFCSP package.

Feature Summary

• High-speed performance with 410 MHz bandwidth and 870 V/µs slew rate
• Rail-to-rail output swing capability for efficient single-supply operation
• Integrated power-down feature for reduced quiescent current consumption
• Wide input common-mode voltage range extending below ground potential

Applications

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

Procurement Notes

Verify the specific ordering suffix R2 indicates a reel quantity of 250 units when sourcing this component. Confirm that the Z suffix denotes RoHS compliance status. Ensure the lead frame chip scale package dimensions match the required PCB footprint constraints. Validate the extended industrial temperature rating against environmental specifications.

Selection Notes

Select this component for applications requiring high-speed signal amplification with low noise characteristics. The rail-to-rail output allows for maximum dynamic range utilization in single-supply designs. Consider the power-down pin functionality for battery-operated systems requiring active standby modes. Evaluate thermal dissipation requirements based on the exposed pad connection to the negative supply rail.

Part Context

This part belongs to the ADA4855 series of high-speed video amplifiers manufactured by Analog Devices. It is designed using the XFCB3 process technology to achieve superior speed and dynamic range. The triple configuration integrates three independent amplifiers into a single compact package, optimizing board space for multi-channel signal paths.

Replacement Considerations

ADA4855-3YCPZ-R7 offers identical electrical specifications but differs in packaging quantity.
