ADA4857-2YCPZ-R7 IC OPAMP VFB 2 CIRCUIT 16LFCSP Analog Devices Inc.

 

GENERAL DESCRIPTION

The ADA4857 is a unity gain stable, high speed, voltage feedback amplifier with low distortion, low noise, and high slew rate. With a spurious-free dynamic range (SFDR) of −88 dBc @ 10 MHz, the ADA4857 is an ideal solution in a variety of applications including ultrasounds, ATE, active filters, and ADC drivers. The Analog Devices, Inc., proprietary next-generation XFCB process and innovative architecture enables such high performance amplifiers.
