ADA4857-2YCPZ-R7

Overview

The Analog Devices ADA4857-2YCPZ-R7 is a dual-channel, unity-gain stable, high-speed voltage feedback operational amplifier. It features an 850 MHz bandwidth and a 2800 V/μs slew rate in the LFCSP package. The device operates on supply voltages ranging from 5 V to 10 V with a quiescent current of approximately 5 mA per amplifier. It includes a power-down feature for reduced consumption and is housed in a 16-lead LFCSP package.

Feature Summary

• High-speed performance with 850 MHz bandwidth and 2800 V/μs slew rate
• Low noise density of 4.4 nV/√Hz and low distortion characteristics
• Integrated power-down pin for reducing quiescent current
• Wide supply voltage range supporting single or dual supply configurations

Applications

• Instrumentation systems
• IF and baseband amplifiers
• Active filters
• ADC drivers
• DAC buffers

Procurement Notes

Verify the specific ordering suffix YCPZ-R7 against the manufacturer's official documentation to confirm the exact package type, temperature grade, and reel packaging specifications. Ensure compatibility with your PCB footprint and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when high dynamic range and precision are required alongside speed. The dual-channel configuration allows for space-efficient designs in applications like ultrasound or ATE. Consider the exposed paddle for thermal dissipation and ensure proper bypassing for optimal performance.

Part Context

This part belongs to the ADA4857 family of ultralow distortion, low power, low noise, high-speed op amps. The -2 variant specifically denotes the dual-channel version, distinct from the single-channel ADA4857-1. It utilizes Analog Devices' proprietary XFCB process for enhanced performance.

Replacement Considerations

Consult the manufacturer's datasheet for officially confirmed substitute part numbers within the same product family or series that match the required channel count and package dimensions.
