RoHS 6 fully compliant options available. IORM peak Example 2: CNR fig 8 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 hcnr201-000 input photodiode PD1 to allow bipolar input currents.

Units Test Conditions Fig. The hhcnr201-000e amplifier acts to stabilize and linearize the light output of the LED. Gull Wing Surface Mount Option It is also possible to convert this circuit into a fully bipolar circuit with a bipolar output signal by using the output of the 6N to drive some CMOS switches to switch hcnr21-000e polarity of PD2 depending on the polarity of the input signal, obtaining a bipolar output voltage swing.

It is advised that normal static precautions be taken in handling and assembly. A Parameter Symbol Input-Output The lower gains, higher input currents and higher offset voltages affect the accuracy of the circuit, datasgeet not the way it operates. Protective cut-out switches must be used to ensure that the safety limits are not exceeded. Data subject to hcn201-000e. Device considered a two-terminal device: Test Parameter Symbol Device Min.

R3 and R5 are selected to provide enough current to drive the bases of Q2 and Q4. Package Outline Drawings The loop current is then divided between R1 and R3. High Speed High Precision 1. This output current generates a voltage across R3, which is then sensed by Datasehet.

Typical photodiode leakage vs. For product information and a complete list of distributors, please go to our website: Diodes D1 and D2 help reduce crossover distortion by keeping both amplifiers active during both positive and negative portions of the input signal. Input photodiode CTR vs.

The circuit operates in the same manner as well; the only hcnr201-0000e is the performance of amplifiers A1 and A2.

External Clearance L IO1 9. Option datasheets are available. Two topologies that allow for bipolar operation are shown in Figure The circuit has a bandwidth of about 1.


The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: In the high-speed circuit discussed above, the input and output circuits are stabilized by reducing the local loop gains of the input and output circuits. To achieve very high linearity for bipolar signals, the gain should be exactly the same for both positive and negative input polarities.


The output photodiode then converts the stable, linear light output of the LED into a current, which can then be converted back into a voltage ratasheet another amplifier.

Example Application Circuits The circuit shown The relationship between the input optical power and the output current of a photodiode is very linear. This allows the designer to make perf- ormance trade-off s that would otherwise be diffi cult An analysis similar to the one above yields the following expression relating output current to input voltage: These capacitors also limit the bandwidth of the circuit to about 10 kHz adtasheet can be used to reduce the output noise of the circuit by dataeheet its bandwidth even further.

IPD2 error to best fit line is the deviation below and above the best fit line, expressed as datasheef percentage of the full scale output.

Of Pins 8 Forward Hcnr201-000 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.
