LOC111 Linear Optocoupler INTEGRATED CIRCUITS DIVISION Parameter Rating Units Description LED Operating Range 2-10 mA The LOC111 Single Linear Optocoupler features an infrared LED optically coupled with two photodiodes. K3, Transfer Gain 0.733-1.072 - 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. High Gain Stability Low Input/Output Capacitance Approvals Low Power Consumption UL Recognized Component: File E76270 8-Pin Flatpack or DIP Package (PCMCIA CSA Certified Component: Certificate 1175739 Compatible) Certified to: Machine Insertable, Wave Solderable IEC60950-1: 2005 Surface Mount and Tape & Reel Versions Available EN60950-1: 2006 VDE Compatible TUV Certificate B 09 07 49410 006 Ordering Information Applications Part Number Description Modem Transformer Replacement With No LOC111 8-Pin DIP (50/Tube) Insertion Loss LOC111P 8-Pin Flatpack (50/Tube) Digital Telephone Isolation LOC111PTR 8-Pin Flatpack (1000/Reel) Power Supply Feedback Voltage/Current LOC111S 8-Pin Surface Mount (50/tube) Medical Sensor Isolation Audio Signal Interfacing LOC111STR 8-Pin Surface Mount (1000/Reel) Isolation of Process Control Transducers K3 Sorted Bins Bin D = 0.733 - 0.805 Bin E = 0.806 - 0.886 Bin F = 0.887 - 0.974 Bin G = 0.975 - 1.072 The LOC111 will be shipped using bins available at date of order.
