Example Application Circuits The circuit shown LED forward voltage vs. IORM peak Example 2: R3 and R5 are selected to provide hcn201-000e current to drive the bases of Q2 and Q4. LED input current vs. A Parameter Symbol Input-Output CNR fig 8 HCNRE datasheet and specification datasheet. Elcodis is a trademark of Elcodis Company Ltd.

High-speed low-cost analog isolator. Units Test Conditions Fig. The output photodiode then converts the stable, linear light output of the LED into a current, adtasheet can then be converted back into a voltage by another amplifier.

Because a photodiode can conduct current in only one direction, two diodes D1 and D2 are used to steer the input current to the appropriate terminal of input photodiode PD1 to allow bipolar input currents.


Of Pins 8 Forward Voltage 1. The two OP-AMPS shown are two separate LM, and not two channels in a single dual package, otherwise the loop side and output side will not be properly isolated. The relationship between the input optical power and the output current of a photodiode is very linear. External Creepage L IO2 IPD2 error to best fit line is the deviation below and above the best fit line, expressed as a percentage of the full scale output.

Pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.


External Clearance L IO1 9. The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: Assuming that A1 is a perfect op-amp, no current flows into the inputs of A1; therefore, all of the current flowing through R1 will flow through PD1.

Loop-powered mA current loop circuits. The output photodiode produces a photocur rent. Gull Wing Surface Mount Option Two example circuits that operate with bipolar input signals are discussed in the next section.


HCNR fig 2 0. For example, when the input signal positive, optocoupler OC1 is active while OC2 is turned off. An analysis similar to the one above yields the following expression relating output current to input voltage: The basic optocoupler con- sists of an LED and two photodiodes.

Figure 13 illustrates how to change the basic circuit to accommodate both positive and negative input and output voltages.

Because the basic circuit operation has not changed, the circuit still has good gain stability. This output current generates a voltage across R3, which is then sensed by R2.

The loop current is then divided between R1 and R3. Contact adtasheet Avago sales representative or authorized distributor for information. Example Application Circuits The circuit shown in Figure 16 is a high-speed low-cost circuit designed for use in the feedback path of switchmode power supplies.
