Description of Operation and Applications
Information
Product Description
The EL8170 and EL8173 are micropower instrumentation
amplifiers (in-amps) which deliver rail-to-rail input
amplification and rail-to-rail output swing on a single 2.9V to
5V supply. The EL8170 and EL8173 also deliver excellent
DC and AC specifications while consuming only 60µA typical
supply current. Because the EL8170 and EL8173 provide an
independent pair of feedback terminals to set the gain and to
adjust output level, these in-amps achieve high common-
mode rejection ratio regardless of the tolerance of the gain
setting resistors. The EL8173 is internally compensated for a
minimum closed loop gain of 10 or greater, well suited for

moderate to high gains. For higher gains, the EL8170 is
internally compensated for a minimum gain of 100. An
ENABLE pin is used to reduce power consumption, typically
2.9µA, while the instrumentation amplifier is disabled.
Input Protection
All input and feedback terminals of the EL8170 and EL8173
have internal ESD protection diodes to both positive and
negative supply rails, limiting the input voltage to within one
diode drop beyond the supply rails. The EL8170 has
additional back-to-back diodes across the input terminals
and also across the feedback terminals. If overdriving the
inputs is necessary, the external input current must never
exceed 5mA. On the other hand, the EL8173 has no clamps
to limit the differential voltage on the input terminals allowing
