ADA4857-1YRZ

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 ADA4857 has 850 MHz bandwidth, 2800 V/us 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 3mm×3mm 8-lead LFCSP and a standard 8-lead SOIC. The ADA4857-2 is available in a 4mm×4mm 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)
