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 at 10 MHz, the
ADA4857 is an ideal solution for 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.
The ADA4857 has 850 MHz bandwidth, 2800 V/s slew rate, and
settles to 0.1% in 15 ns. With a wide supply voltage range (5 V to
10 V), the ADA4857 is an ideal candidate for systems that require
high dynamic range, precision, and speed.
The ADA4857-1 amplifier is available in a 3 mm × 3 mm, 8-lead
LFCSP and a standard 8-lead SOIC. The ADA4857-2 is available in
a 4 mm × 4 mm, 16-lead LFCSP. The LFCSP features an exposed
paddle that provides a low thermal resistance path to the printed
circuit board (PCB). This path enables more efficient heat transfer
and increases reliability. The ADA4857 works over the extended
industrial temperature range (40°C to +125°C).
