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.
