ADA4857-2 Ultralow Distortion, Low Power, Low Noise, High Speed Op Amp _ BDTIC a Leading Distributor in China

ADA4857-2 Ultralow Distortion, Low Power, Low Noise, High Speed Op Amp

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 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/μs 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 LFSCP. 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).
