Servo-current gain (K1) is the ratio of the feedback photodiode current (I
P1
) to the input LED current (I
F
) current (I
F
), i.e. K1 = I
P1
/I
F
.
Forward gain (K2 is the ratio of the output photodiode current (I
P2
) to the input LED current (I
F
), i.e. K2 = I
P2
/I
F
.
§
Transfer gain (K3) is the ratio of the forward gain to the servo-current gain, i.e. K3 = K2/K1.
Transfer gain linearity
(
K3) is the percent deviation of the transfer gain K3 as a function of LED input current (I
F
) or the package temperature.
