3.9 D/A Output
Leadshine SMC6480 provides 2 channel 8 bit D/A output with a voltage follower. Because the operational amplifier
is powered by a single 5VDC, the D/A output is between 0.07V and 4.45V. Figure 3-18 is the interface circuit of D/A
output. If 0V output is required, contact Leadshine to modify the SMC6480 for 0~2.5V D/A output.

3.10 Encoder Input EA, EB and EZ
Leadshine SMC6490/PMC6496 accepts differential encoder input which includes channel A signal EA, channel B
signal EB and Z index signal EZ. EA and EB are used for pulses counting. EZ can be taken as index signal. See
figure 3-17.
