The feedback photodiode captures a percentage of the LED's 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.
The time and temperature stability of the input-output coupler gain (K3) is insured by using matched PIN photodiodes that accurately track the output flux of the LED.
A typical application circuit (Figure 1) uses an operational amplifier at the circuit input to drive the LED.
The feedback photodiode sources current to R1 connected to the inverting input of U1.
The photocurrent, IP1, will be of a magnitude to satisfy the relationship of (IP1=VIN /R1).
