† This symbol is not currently listed within EIA or JEDEC standards for semiconductor symbology.

‡ Servo current gain (K1) is the ratio of the feedback photodiode current (IP1) to the input LED current (IF) current (IF), i.e. K1 = IP1/IF.

§ Forward gain (K2 is the ratio of the output photodiode current (IP2) to the input LED current (IF), i.e. K2 = IP2/IF.

¶ Transfer gain (K3) is the ratio of the forward gain to the servo 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 (IF) or the package temperature.
