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).

Product Detail

These evaluation boards are designed to help users evaluate the ADA4857-2. The evaluation board is a BARE BOARD. There are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.


The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials
