ADA4857-1YRZ

Overview

The Analog Devices ADA4857-1YRZ is a high-speed, voltage feedback operational amplifier featuring ultralow distortion and low noise. It offers an 850 MHz bandwidth (LFCSP) or 750 MHz (SOIC), a 2800 V/μs slew rate, and settles to 0.1% in 15 ns. The device operates on a wide supply range of 5 V to 10 V with a quiescent current of 5 mA per amplifier. It includes a power-down feature and is available in 3 mm × 3 mm 8-lead LFCSP and 8-lead SOIC packages.

Feature Summary

High-speed performance with 850 MHz bandwidth and 2800 V/μs slew rate
Ultralow distortion and low noise characteristics for precision signal conditioning
Integrated power-down pin reduces quiescent current consumption
Wide supply voltage operation from 5 V to 10 V

Applications

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

Procurement Notes

Verify the specific package suffix matches the required form factor: 'Y' indicates the 3 mm × 3 mm 8-lead LFCSP, while 'R' denotes the 8-lead SOIC. Confirm that the ordering code corresponds exactly to the single-channel configuration. Ensure the datasheet revision aligns with the manufacturing lot for accurate thermal and electrical specifications.

Selection Notes

Select this component for applications requiring high dynamic range and speed within a compact footprint. The LFCSP variant provides superior thermal dissipation via an exposed paddle compared to the SOIC option. Consider the power-down functionality if system-level power management is critical. Verify capacitive load drive capabilities against the specific application requirements.

Part Context

This part belongs to the ADA4857 family of high-speed operational amplifiers manufactured by Analog Devices. It utilizes the proprietary XFCB process to achieve high performance metrics. The family includes both single-channel (ADA4857-1) and dual-channel (ADA4857-2) variants, designed for demanding analog signal processing tasks.
