EL8171, EL8172
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.
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.
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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
