LOC110 Single Linear Optocoupler INTEGRATED CIRCUITS DIVISION Parameter Rating Units Description LED Operating Range 2 - 10 mA The LOC110 Single Linear Optocoupler features an infrared LED optically coupled with two photodiodes. K3, Transfer Gain 0.668 - 1.179 - 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 for the LED s nonlinear time and temperature Features characteristics. The other (output) photodiode 0.01% Servo Linearity provides an output signal that is linear with respect THD -87dB Typical to the servo LED current. The product features Wide Bandwidth (>200kHz) wide bandwidth, high input to output isolation, and Couples Analog and Digital Signals excellent servo linearity.
