Precision Linear Optocoupler

The TIL300 precision linear Optocoupler TIL300 TIL300A consists of an infrared LED irradiating an isolated feedback Photodiode and an output Photodiode in a bifurcated arrangement. The feedback Photodiode captures a percentage of the flux of the LED that CAN be used to generate a control signal to regulate the LED drive current. This technique is used to compensate for the nonlinear time and temperature characteristics of the LED The output-side Photodiode then produces an output signal that is linearly proportional to the servo-optical flux emitted from the LED A typical application circuit (shown in Figure 1) uses an Operational Amplifier as the input to drive the LED The feedback Photodiode sources current through R1, which is connected to the inverting input of the input Operational Amplifier The photocurrent IP1 assumes a magnitude that satisfies the relationship IP1 = VI/R1. The magnitude of the current is directly proportional to the LED current through the feedback transfer gain K1(VI/R1 = K1 IF). The Operational Amplifier supplies LED current to produce sufficient photocurrent to keep the node voltage Vb equal to node voltage Va By Unkown
