GENERAL DESCRIPTION
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
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.
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.
The ADA4896-2 is available in 8-lead LFCSP and 8-lead MSOP
packages. The ADA4897-1 is available in 8-lead SOIC and 6-lead
SOT-23 packages. The ADA4897-2 is available in a 10-lead MSOP
the extended industrial temperature range of 40°C to +125°C.
