ADA4857-1YCPZ-R7

Overview

The Analog Devices ADA4857-1YCPZ-R7 is a single-channel, unity-gain stable, high-speed voltage feedback operational amplifier. It features an 850 MHz bandwidth and a 2800 V/μs slew rate. The device operates on a supply voltage range of 5 V to 10 V with a quiescent current of 5 mA per amplifier. It includes a power-down feature and is housed in a 3 mm × 3 mm 8-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 for precision signal conditioning
• Integrated power-down pin reduces quiescent current consumption
• Ultralow distortion characteristics suitable for dynamic applications

Applications

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

Procurement Notes

Verify the specific ordering suffix YCPZ-R7 against official documentation to confirm the exact package type and reel quantity. Ensure compatibility with the required operating temperature range and supply voltage specifications before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high-speed signal processing with low power consumption. Consider the exposed paddle thermal management requirements inherent to the LFCSP package. Evaluate the power-down functionality if system-level power savings are necessary during idle periods.

Part Context

This part belongs to the ADA4857 family of ultralow distortion, low power, low noise, high-speed op amps. The -1 designation indicates a single-channel configuration, distinguishing it from dual-channel variants within the same series.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Do not assume functional equivalence with other high-speed amplifiers without verifying pinout and electrical parameter alignment.
