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 LED.

IP1, will be of a magnitude to satisfy the relationship of
(IP1 = VIN/R1).
Photodiode
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 current to force sufficient photocurrent to keep
the node voltage (Vb) equal to Va.
A silicon diode operating as a current source. The out-
put current is proportional to the incident optical flux
supplied by the LED emitter. The diode is operated in
the photovoltaic or photoconductive mode. In the pho-
tovoltaic mode the diode functions as a current
source in parallel with a forward biased silicon diode.
The magnitude of the output current and voltage is
dependent upon the load resistor and the incident
LED optical flux. When operated in the photoconduc-
tive mode the diode is connected to a bias supply
which reverse biases the silicon diode. The magni-
tude of the output current is directly proportional to the
LED incident optical flux.
The output photodiode is connected to a non-invert-
ing voltage follower amplifier. The photodiode load
resistor, R2, performs the current to voltage conver-
sion. The output amplifier 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
LED (Light Emitting Diode)
An infrared emitter constructed of AlGaAs that emits
at 890 nm operates efficiently with drive current from
500 µA to 40 mA. Best linearity can be obtained at
drive currents between 5.0 mA to 20 mA. Its output
flux typically changes by - 0.5 % /°C over the above
operational current range.
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 output 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

In applications such as monitoring the output voltage
from a line powered switch mode power supply, mea-
suring bioelectric signals, interfacing to industrial
transducers, or making floating current measure-
ments, a galvanically isolated, DC coupled interface
is often essential. The IL300 can be used to construct
an amplifier that will meet these needs.

R5 can determined using the following equation,
The control amplifier consists of a voltage divider and
a non-inverting unity gain stage. The TDA4918 data
sheet indicates that an input to the control amplifier is
a high quality operational amplifier that typically
requires a +3.0 V signal. Given this information, the
amplifier circuit topology shown in Figure 18 is
selected.

Or if a unity gain amplifier is being designed (VMON-
ITOR = VOUT, R1 = 0), the equation simplifies to:
The power supply voltage is scaled by R1 and R2 so
that there is + 3.0 V at the non-inverting input (Va) of
U1. This voltage is offset by the voltage developed by
photocurrent flowing through R3. This photocurrent is

created by current flowing through the LED. Thus as
the scaled monitor voltage (Va) varies it will cause a
change in the LED current necessary to satisfy the dif-
ferential voltage needed across R3 at the inverting
input.
The first step in the design procedure is to select the
value of R3 given the LED quiescent current (IFq) and
the servo gain (K1). For this design, IFq = 12 mA. Fig-
ure 4 shows the servo photocurrent at IFq is found to
be 100 µA. With this data R3 can be calculated.

The last step in 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.

The circuit was constructed with an LM201 differential
operational amplifier using the resistors selected. The
amplifier was compensated with a 100 pF capacitor

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.

The AC characteristics are also quite impressive
offering a - 3.0 dB bandwidth of 100 kHz, with a -45 °
phase shift at 80 kHz as shown in Figure 21.

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.

Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as
their impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are
known as ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs
and forbid their use within the next ten years. Various national and international initiatives are pressing for an
earlier ban on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use
of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments
respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting
substances and do not contain such substances.
We reserve the right to make changes to improve technical design
and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each
customer application by the customer. Should the buyer use Vishay Semiconductors products for any
unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all
claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal
damage, injury or death associated with such unintended or unauthorized use.
