DATASHEET
Micropower, Single Supply, Rail-to-Rail Input-Output
Instrumentation Amplifiers
EL8170, EL8173
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.
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.
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).

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on
reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see device information
page for EL8170, EL8173 For more information on MSL, please see
tech brief TB363.
