LOC211P

LOC211P 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 Description The LOC211P 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 • Certified to: • EN 60950 • EN 41003 Pin Configuration LOC211 Pinout 1 2 + LED 3 + Vcc 4 I1 NC NC +Vcc 8 I1 9 I2 5 6 7 12 11 10 13 16 15 14 Ordering Information Part # LOC211P LOC211PTR NC NC +Vcc I2 – LED + LED +Vcc Description 16 Pin Flatpack (50/Tube) 16 Pin Flatpack (1000/Reel) – LED K3 Sorted Bins Bin 1 = 0.733 - 0.886 Bin 2 = 0.887 - 1.072 Bin Matrix Suffix Bin Top Pole Bottom Pole Optocoupler* Optocoupler** 1 1 1 2 2 1 2 2 K L M N *Top Pole Optocoupler: Pins 1,2,3,4,13, and 14 **Bottom Pole Optocouplers: Pins 7 through 12 • Orders for the LOC211P product will be shipped using bins available at the date of the order. Any bin can be shipped. Part Number Information The LOC211 are shipped in anti-static tubes (50 pieces each) or tape/reel (1,000 pieces each).
