GENERAL DESCRIPTION  
The ADA4896-2/ADA4897-1/ADA4897-2 are unity-gain stable,  
low noise, rail-to-rail output, high speed voltage feedback amplifiers  
that have a quiescent current of 3 mA. With a 1/f noise of  
2.4 nV/√Hz at 10 Hz and a spurious-free dynamic range of −80 dBc  
at 2 MHz, the ADA4896-2/ADA4897-1/ADA4897-2 are ideal  
solutions in a variety of applications, including ultrasound, low  
noise preamplifiers, and drivers of high performance ADCs. The  
Analog Devices, Inc., proprietary next-generation SiGe bipolar  
process and innovative architecture enable such high performance  
amplifiers.

The ADA4896-2/ADA4897-1/ADA4897-2 have 230 MHz  
bandwidth, 120 V/μs slew rate, and settle to 0.1% in 45 ns.  
With a wide supply voltage range of 3 V to 10 V, the ADA4896-2/  
ADA4897-1/ADA4897-2 are ideal candidates for systems that  
require high dynamic range, precision, low power, and high speed.
