The EL817 series of devices each consist of infrared emitting diodes, optically coupled to a phototransistor detector. They are packaged in a 4-pin DIP package and available in wide-lead spacing and SMD options.
The EL817 is a micropower instrumentation amplifier optimized for single-supply operation over the +2.4V to +5.5V range. Inputs and outputs can operate rail-to-rail. The EL817 also delivers excellent DC and AC specifications while consuming only 65µA typical supply current. As with all instrumentation amplifiers, a pair of inputs provide very high common-mode rejection and are completely independent of 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 EL817 is compensated for a gain of 100 or more, also it has 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 EL817 input range includes ground to slightly above positive rail. The output stage swings to the ground and positive supply (no pull-up or pull-down resistors are needed).
