Littelfuse, Inc. Linear Optocouplers Series LOC117

Littelfuse linear optocouplers feature an infrared LED optically coupled with two photodiodes. One feedback (input) photodiode is used to generate a control signal that provides a servomechanism to the LED drive current, thus compensating for the LED's nonlinear time and temperature characteristics. The other (output) photodiode provides an output signal that is linear with respect to the servo LED current. The devices feature wide bandwidth, high input to output isolation, and excellent servo linearity. Features: 0.01% Servo Linearity THD -87dB Typical Wide Bandwidth (>200kHz) Couple Analog and Digital Signals High Gain Stability Low Input-to-Output Capacitance Low Power Consumption VDE Compatible Flatpack Package (PCMCIA Compatible) Surface Mount and Tape & Reel Versions Available
