EXAMPLE APPLICATIONS
Rev D4, Page 35/39
Figure 12 is a circuit diagram of an optical encoder with
an incremental output of quadrature signals as RS422-
compatible differential signals which can be terminated
by 100 Ω at the controller end. By way of an alterna-
tive the magnetic encoder in Figure 13 uses magneto-
resistive sensor bridges. An external overvoltage pro-
tection circuit may be realized employing TVS diodes
plus a PolyFuse in the VDD line, for instance.
