ADA4857-1YCPZ-R2

Overview

The ADA4857-1YCPZ-R2 is a single-channel, unity-gain stable, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features an 850 MHz bandwidth and a 2800 V/μs slew rate in the LFCSP package. The device operates on a wide supply voltage range of 5 V to 10 V with a quiescent current of 5 mA per amplifier. It incorporates a power-down feature for reduced consumption and utilizes an exposed paddle for thermal management.

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 active energy management
• Exposed paddle design for efficient heat dissipation

Applications

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

Procurement Notes

Verify the specific ordering suffix YCPZ-R2 against official documentation to confirm the exact tape-and-reel packaging quantity and variant specifications. Ensure compatibility with the required 3 mm × 3 mm 8-lead LFCSP footprint and exposed pad thermal requirements during procurement planning.

Selection Notes

Select this component when high dynamic range and precision are required alongside speed. The wide supply voltage range supports various system architectures. Consider the exposed paddle connection options (GND or VS) for optimal thermal performance and reliability in dense PCB layouts.

Part Context

This part belongs to the ADA4857 family, which includes both single-channel (ADA4857-1) and dual-channel (ADA4857-2) variants. The series is designed using Analog Devices' proprietary XFCB process to achieve high performance metrics while maintaining low power consumption across industrial temperature ranges.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers before implementation.
