LOC210
Linear Optocouplers
Features * 16 Pin SOIC 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
Description The LOC210 Dual 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.
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
Approvals * UL Recognized: File Number E76270 * CSA Certified: File Number LR 43639-10 * BSI Certified: * BS EN 60950:1992 (BS7002:1992) Certificate #:7344 * BS EN 41003:1993 Certificate #:7344

Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.
