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. …
