The output photodiode produces a photocur rent. Figure 13 illustrates how to change the basic circuit to accommodate both positive and negative input and output voltages. Option datasheets are available.

Page 19 The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and dattasheet two output signals: Parameter Symbol Device Min. Isolator for thermo couples 4 mA to 20 mA loop isola. The loop current is then divided between R1 and R3. However, an additional amplifier is used to provide an appropriate offset voltage to the other amplifiers that exactly cancels the diode voltage drops to maintain circuit accuracy.

The first circuit has the obvious advantage of requiring only one hfnr201-000e however, the offset performance of the circuit is dependent on the matching of IOS1 and IOS2 and is also dependent on the gain of the optocoupler. The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only datsheet optocoupler and generates two output signals: 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 by another amplifier.

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. As a result, the non-linearity. The basic optocoupler con- sists of an LED and two photodiodes. Input photodiode CTR 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 datsaheet flows through R3. K3 is calculated from the slope of the best fit hcr201-000e of IPD2 vs.

The circuit operates in the same manner as well; the only difference is the performance of catasheet A1 and A2. 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. Two example circuits that operate with bipolar input signals are discussed in the next section.

High Speed High Precision 1. As mentioned above, only one optocoupler is used. R3 and R5 are selected to provide enough current to drive the bases of Q2 and Q4. 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 the polarity of PD2 depending on the polarity of the input signal, obtaining a bipolar output voltage swing.

LED input current vs. Besides the optocoupler, two external op-amps and two resistors are required. Device considered a two-terminal device: Pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.

An analysis hchr201-000e to the one above yields the following expression relating output current to input voltage: Gull Wing Surface Mount Option Copy your embed code and put on your site: 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. Two topologies that allow for bipolar operation are shown in Figure 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.
