Example Application Circuits The circuit shown Protective cut-out switches must be used to ensure that the safety limits are not exceeded. The input pho- todiode hcnr2201-000e be used to monitor, and therefore stabilize, the light output of the LED Loop-powered mA current loop circuits.

Units Test Conditions Fig. Typical photodiode leakage vs. The output circuit does not directly generate an output voltage which is sensed by R2, it instead uses Q1 to generate an output current which flows through R3.

Two example circuits that operate with bipolar input signals are discussed in the next section. Parameter Symbol Device Min. Option datasheets are available.

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. As mentioned above, only one optocoupler is used. Also notice that IPD1 is exactly proportional to VIN, giving a very linear relationship between the input voltage and the photodiode current. The circuit has a bandwidth of about 1. Of Pins 8 Forward Voltage 1. Absolute Maximum Ratings Storage Temperature High Speed High Precision 1.


Diodes D1 and D2 help reduce crossover distortion by keeping both amplifiers active during both positive and negative portions of the input signal.

Copy your embed code and put on your site: This allows the designer to make perf- ormance hcnr210-000e s that would otherwise be diffi cult It is advised that normal static precautions be taken in handling and datashfet.

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.

Specific performance will depend on circuit topology and components. Download datasheet Kb Share this hvnr201-000e.

Page 19 The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: Contact your Avago sales representative or authorized distributor for information. K3 is calculated from the slope of the best fit eatasheet of IPD2 vs.


The input terminals of the op-amps and the photodiodes are connected in the circuit using Kelvin connections to help ensure the accuracy of the circuit. LED forward voltage vs.

Hnr201-000e example, when the input signal positive, optocoupler OC1 is active while OC2 is turned off. LED input current vs.

To achieve very high linearity for bipolar signals, the gain should dayasheet exactly the same for both positive and negative input polarities. Gull Wing Surface Mount Option As a result, the non-linearity.

Because the basic circuit operation has not changed, the circuit still has good gain stability. Data subject to change.
