LOC117 Linear Optocoupler INTEGRATED CIRCUITS DIVISION Parameter Rating Units Description LED Operating Range 2-10 mA The LOC117 Single Linear Optocoupler features an K3, Transfer Gain 0.887-1.072 - infrared LED optically coupled with two photodiodes. One feedback (input) photodiode is used to generate Isolation, Input to Output 3750 V rms a control signal that provides a servomechanism to the LED drive current, thus compensating Features for the LED s nonlinear time and temperature 0.01% Servo Linearity characteristics. The other (output) photodiode THD -87dB Typical provides an output signal that is linear with respect Wide Bandwidth (>200kHz) to the servo LED current. The product features Couples Analog and Digital Signals wide bandwidth, high input to output isolation, and High Gain Stability excellent servo linearity.
