Linear Optocoupler, High Gain Stability, Wide Bandwidth
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.
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.

Notes
• Minimum and maximum values were tested requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements
(1) Bin sorting: K3 (transfer gain) is sorted into bins that are ± 6 %, as follows:
Bin A = 0.557 to 0.626
Bin B = 0.620 to 0.696
Bin C = 0.690 to 0.773
Bin D = 0.765 to 0.859
Bin E = 0.851 to 0.955
Bin F = 0.945 to 1.061
Bin G = 1.051 to 1.181
Bin H = 1.169 to 1.311
Bin I = 1.297 to 1.456
Bin J = 1.442 to 1.618
K3 = K2/K1. K3 is tested at IF = 10 mA, Vdet = -15 V
(2) Bin categories: All IL300s are sorted into a K3 bin, indicated by an alpha character that is marked on the part. The bins range from “A”
through “J”.
The IL300 is shipped in tubes of 50 each. Each tube contains only one category of K3. The category of the parts in the tube is marked on
the tube label as well as on each individual part
(3) Category options: standard IL300 orders will be shipped from the categories that are available at the time of the order. Any of the ten
categories may be shipped. For customers requiring a narrower selection of bins, the bins can be grouped together as follows:
IL300-DEFG: order this part number to receive categories D, E, F, G only
IL300-EF: order this part number to receive categories E, F only
IL300-E: order this part number to receive category E only
