The magnitude of this current is directly proportional to the feedback transfer gain

(K1) times the LED drive current (V /R1=K1 • I ). The op-amp will supply LED cur-

DESCRIPTION

rent to force sufﬁcient photocurrent to keep the node voltage (Vb) equal to Va

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 ﬂux and generates a control

The output photodiode is connected to a non-inverting voltage follower ampliﬁer. The

photodiode load resistor, R2, performs the current to voltage conversion. The output

ampliﬁer voltage is the product of the output forward gain (K2) times the LED current

and photodiode load, R2 (V =I • K2 • R2).

Therefore, the overall transfer gain (V /V ) 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 V /V =

signal (IP ) 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

(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 [V /

signal (IP ) that is linearly related to the

V =K3 (R2/R1)].

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.
