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).
