GENERAL DESCRIPTION
The
rail-to-rail output, high speed voltage feedback amplifiers
that have a quiescent current of 3 mA. With the 1/f noise of
2.4 nV/√Hz at 10 Hz and a spurious-free dynamic range of
−80 dBc at 2 MHz, the
solution 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.
TheADA4896-2/ADA4897-1
120 V/μs slew rate, and settle to 0.1% in 45 ns. With a wide
supply voltage range (3 V to 10 V), the ADA4896-2/ADA4897-1
are ideal candidates for systems that require high dynamic
range, precision, and high speed.
The
packages. The
6-lead SOT-23 packages. Both the
work over the extended industrial temperature range of −40°C
to +125°C.
