Rev 6.00
October 9, 2015 Micropower, Single Supply, Rail-to-Rail Input-Output Instrumentation Amplifiers
The EL8171 and EL8172 are micropower instrumentation
amplifiers optimized for single supply operation over the
+2.4V to +5.5V range. Inputs and outputs can operate
rail-to-rail. As with all instrumentation amplifiers, a pair of
inputs provide very high common-mode rejection and are
completely independent from a pair of feedback terminals.
The feedback terminals allow zero input to be translated to
any output offset, including ground. A feedback divider
controls the overall gain of the amplifier. Features The EL8172 is compensated for a gain of 100 or more, and
the EL8171 is compensated for a gain of 10 or more. The
EL8171 and EL8172 have PMOS input devices that provide
sub-nA input bias currents. 170kHz -3dB bandwidth (G = 100) The amplifiers can be operated from one lithium cell or two
Ni-Cd batteries. The EL8171 and EL8172 input range goes
from below ground to slightly above positive rail. The output
stage swings completely to ground (ground sensing) or
positive supply -no pull-up or pull-down resistors are
needed. 95ВµA maximum supply current Maximum input offset voltage
