Figure 3. THAT1200P typical application circuit
If, however, there is the possibility of a DC voltage
appearing across the inputs of the line receiver, a
portion of that voltage will appear directly across the
terminals of capacitor Cb. In that case, choose the
capacitor’s voltage rating so that it is capable of han-
dling the expected level of DC voltage. If the polarity
of the DC voltage is unknown, or may swing to either
polarity, the use of a non-polarized electolytic is
highly recommended.
