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
LED’s flux and generates a control signal (IP1) that
can be used to servo the LED drive current. This tech-
nique compensates for the LED’s non-linear, time,
and temperature characteristics. The output PIN pho-
todiode 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.

1. Bin Sorting:
K3 (transfer gain) is sorted into bins that are ± 6 % , as follows:
Bin A = 0.557 - 0.626
Bin B = 0.620 - 0.696
Bin C = 0.690 - 0.773
Bin D = 0.765 - 0.859
Bin E = 0.851 - 0.955
Bin F = 0.945 - 1.061
Bin G = 1.051 - 1.181
Bin H = 1.169 - 1.311
Bin I = 1.297 - 1.456
Bin J = 1.442 - 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, four different bin option parts are offered.
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.

wwwT.DhaetalSahset est4teUp.coinm the design is selecting the LED cur-
rent limiting resistor (R4). The output of the opera-
tional amplifier is targeted to be 50 % of the VCC, or
2.5 V. With an LED quiescent current of 12 mA the
typical LED (VF) is 1.3 V. Given this and the opera-
tional output voltage, R4 can be calculated.
R4 = Vopamp - VF = 2.5 V - 1.3 V = 100Ω
IFq 12 mA

The circuit was constructed with an LM201 differential
operational amplifier using the resistors selected. The
amplifier was compensated with a 100 pF capacitor
connected between pins 1 and 8.
The DC transfer characteristics are shown in Figure
19. The amplifier was designed to have a gain of 0.6
and was measured to be 0.6036. Greater accuracy
can be achieved by adding a balancing circuit, and
potentiometer in the input divider, or at R5. The circuit
shows exceptionally good gain linearity with an RMS
error of only 0.0133 % over the input voltage range of
4.0 V - 6.0 V in a servo mode; see Figure 20.

Figure 21. Amplitude and Phase Power Supply Control
The same procedure can be used to design isolation
amplifiers that accept bipolar signals referenced to
ground. These amplifiers circuit configurations are
shown in Figure 22. In order for the amplifier to
respond to a signal that swings above and below
ground, the LED must be pre biased from a separate
source by using a voltage reference source (Vref1). In
these designs, R3 can be determined by the following
equation.
R3 = Vref1 = Vref1
