LOC112 Linear Optocouplers Features * 8 Pin Flatpack or DIP Package (PCMCIA Compatible) * Couples Analog and Digital Signals * Wide Bandwidth (>200kHz) * High Gain Stability * Low Input/Output Capacitance * Low Power Consumption * 0.01% Servo Linearity * THD 87dB Typical * Machine Insertable, Wave Solderable * Surface Mount and Tape Reel Versions Available * VDE Compatible Applications * Modem Transformer Replacement With No Insertion Loss * Digital Telephone Isolation * Power Supply Feedback Voltage/Current * Medical Sensor Isolation * Audio Signal Interfacing * Isolation of Process Control Transducers Description The LOC112 Single Linear Optocoupler features an infrared LED optically coupled with two phototransistors. One feedback (input) phototransistor is used to generate a control signal that provides a servomechanism to the LED drive current, thus compensating for the LEDs nonlinear time and temperature characteristics. The other (output) phototransistor provides an output signal that is linear with respect to the servo LED current. The product features wide bandwidth, high input to output isolation and excellent servo linearity.
