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.
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.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTE:
4. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise
noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications V+ = +5V, V- = GND, VCM = 1/2V+, RL = Open, TA = +25°C, unless otherwise specified. Boldface limits apply
over the operating temperature range, -40°C to +125°C.
