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 @ 10 MHz,  
the ADA4857 is an ideal solution in 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 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).
