DESCRIPTION
The IL300 Linear Optocoupler consists of
an AlGaAs IRLED irradiating an isolated
feedback and an output PIN photodiode
in a bifurcated arrangement. The feed-
back photodiode captures a percentage
of the LED's ux and generates a control
signal (IP1) that can be used to servo the
LED drive current. This technique com-
pensates for the LED's non-linear, time,
and temperature characteristics. The out-
put PIN photodiode produces an output
signal (IP2) that is linearly related to the
servo optical ux 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 ux of the
LED.
A typical application circuit (Figure 1)
uses an operational amplier at the circuit
input to drive the LED. The feedback
photodiode sources current to R1 con-
nected to the inverting input of U1. The
photocurrent, IP1, will be of a magnitude
to satisfy the relationship of (IP1=VIN /R1).
DESCRIPTION (continued)
The magnitude of this current is directly proportional to the feedback transfer gain
(K1) times the LED drive current (VIN /R1=K1 IF). The op-amp will supply LED cur-
rent to force sufcient photocurrent to keep the node voltage (Vb) equal to Va
The output photodiode is connected to a non-inverting voltage follower amplier. The
photodiode load resistor, R2, performs the current to voltage conversion. The output
amplier voltage is the product of the output forward gain (K2) times the LED current
and photodiode load, R2 (VO=IF K2 R2).
Therefore, the overall transfer gain (VO/VIN) becomes the ratio of the product of the
output forward gain (K2) times the photodiode load resistor (R2) to the product of the
feedback transfer gain (K1) times the input resistor (R1). This reduces to VO/VIN=
(K2 R2)/(K1 R1). The overall transfer gain is completely independent of the LED
forward current. The IL300 transfer gain (K3) is expressed as the ratio of the ouput
gain (K2) to the feedback gain (K1). This shows that the circuit gain becomes the
product of the IL300 transfer gain times the ratio of the output to input resistors [VO/
VIN=K3 (R2/R1)].
