ADA4857-2YCPZ-R2

Overview

The ADA4857-2YCPZ-R2 is a dual-channel, unity-gain stable, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features an ultralow distortion architecture with a spurious-free dynamic range of −88 dBc at 10 MHz and a slew rate of 2800 V/μs. The device operates within a wide supply voltage range of 5 V to 10 V and includes a dedicated power-down feature for reduced quiescent current consumption. Packaged in a 4 mm × 4 mm 16-lead LFCSP with an exposed paddle for efficient thermal dissipation, it supports extended industrial operating temperatures from −40°C to +125°C.

Feature Summary

• High-speed performance with 850 MHz bandwidth and 2800 V/μs slew rate

• Active filter implementations
• Analog-to-digital converter (ADC) drivers
• Digital-to-analog converter (DAC) buffers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm that the component meets all relevant environmental compliance standards required for the target application before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that demand high bandwidth combined with minimal harmonic distortion. The dual-channel configuration allows for cost-effective implementation of differential signal paths or matched amplifier stages. Consider the exposed paddle requirement for optimal thermal management during layout design.

Part Context

This part belongs to the ADA4857 family of high-speed operational amplifiers developed using Analog Devices' proprietary XFCB process technology. The series provides a balance of speed, low noise, and power efficiency. The dual-channel variant consolidates two identical amplifier channels into a single compact package, facilitating space-constrained board designs.

Replacement Considerations

Consult the manufacturer's official documentation for verified substitute part numbers. Cross-referencing should be limited to components explicitly listed as direct replacements or functional equivalents in the datasheet.
