August 11, 2015 Micropower, Single Supply, Rail-to-Rail Input-Output Instrumentation Amplifiers
The EL8170 and EL8173 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 EL8170 is compensated for a gain of 100 or more, and the
EL8173 is compensated for a gain of 10 or more. The EL8170
and EL8173 have bipolar input devices for best offset and
1/f noise performance. 192kHz -3dB bandwidth (G = 100) The amplifiers can be operated from one lithium cell or two
Ni-Cd batteries. The EL8170 and EL8173 input range includes
ground to slightly above positive rail. The output stage swings
to ground and positive supply (no pull-up or pull-down resistors
are needed). Pin Configurations IN-2 +
