Application Notes
The logic circuits in Figures 22 and 23 illustrate two
techniques for interfacing a quadrature output
encoder with a system’s microprocessor.
Figure 22: Typical Circuit for Producing Direction
(up/down) and Magnitude (count) Signals
Figure 23: Typical Circuit for Producing Count Up and
Count Down Signal
If necessary, rise/fall times can be reduced using the
inverters as illustrated in Figure 24.
Figure 24: Circuit for Reducing Signal Rise/Fall Times
The typical switch time for the ASIC used in the EN
Series is 500 nanoseconds. In applications where
high-speed transition times are encountered, voltage
spikes may cause a code output error. To eliminate
the voltage spikes, we suggest placing a 0.01mf
capacitor in the circuit between Vcc and GND.
