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.
