... HCPL-7840. A differential output voltage is created on the other side of the HCPL-7840 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit ...

... As shown in Figure 18, 0.1 µF bypass capacitors (C1, C2) should be located as close as possible to the pins of the HCPL-7840. The bypass capacitors are required because of the high-speed digital nature of the signals inside the HCPL-7840. A 0.01 µF bypass capacitor (C2) is also rec- ommended at the input due to the switched-capacitor POSITIVE FLOATING ...

... HCPL-7840; this minimizes the loop area of the connection and reduces the possibility of stray mag- netic fields from interfering with the measured signal. If the sense resistor is not located on the same PC board as the HCPL-7840 circuit, a tightly twisted pair of wires can accomplish the same thing. ...

... GND1 (pin 4), with the power-supply return path functioning as the sense line to the negative termi- nal of the current sense resistor. This allows a single pair of wires or PC board traces to connect the HCPL-7840 circuit to the sense resistor. By referencing the input circuit to the negative side of the sense resistor, any load ...

... C at least 100 pF works well.) 2.4: How do I ensure that the HCPL-7840 is not destroyed as a result of short circuit conditions which cause voltage drops across the sense resistor that exceed the ratings of the HCPL-7840’s inputs? Select the sense resistor so that it will have less than 5 V drop when short circuits occur ...

... ACCURACY 4.1: Can the signal to noise ratio be improved? Yes. Some noise energy exists beyond the 100 kHz bandwidth of the HCPL-7800(A). Additional filtering using different filter R,C values in the post-amplifier application circuit can be used to improve the signal to noise ratio. For example, by using values kΩ 470 pF in the application circuit the rms output noise will be cut roughly by a factor applications needing only a few kHz bandwidth even better noise performance can be obtained. The noise spectral density is roughly 500 nV/√ ...
