GENERAL DESCRIPTION
The ADA4857 is a unity-gain stable, high speed, voltage feedback 10 V), the ADA4857 is an ideal candidate for systems that require amplifier with low distortion, low noise, and high slew rate. With a high dynamic range, precision, and speed. spurious-free dynamic range (SFDR) of −88 dBc at 10 MHz, the The ADA4857-1 amplifier is available in a 3 mm × 3 mm, 8-lead ADA4857 is an ideal solution for a variety of applications, including LFCSP and a standard 8-lead SOIC. The ADA4857-2 is available in ultrasounds, ATE, active filters, and ADC drivers. The Analog a 4 mm × 4 mm, 16-lead LFCSP. The LFCSP features an exposed Devices, Inc., proprietary next-generation XFCB process and paddle that provides a low thermal resistance path to the printed innovative architecture enables such high performance amplifiers. circuit board (PCB). This path enables more efficient heat transfer The ADA4857 has 850 MHz bandwidth, 2800 V/μs slew rate, and and increases reliability. The ADA4857 works over the extended settles to 0.1% in 15 ns. With a wide supply voltage range (5 V to industrial temperature range (−40°C to +125°C).
