IL300隔离器的光隔离器-晶体管光电输出规格书PDF中文资料

DESCRIPTION

The IL300 linear optocoupler consists of an AlGaAs IRLED irradiating an isolated feedback and an output PIN photodiode in a bifurcated arrangement. The feedback photodiode captures a percentage of the LEDs flux and generates a control signal (IP1) that can be used to servo the LED drive current. This technique compensates for the LED’s non-linear, time, and temperature characteristics. The output PIN photodiode produces an output signal (IP2) that is linearly related to the servo optical flux created by the LED.
