NOTE!
On the PPC-2050, each consecutive pair of analog
outputs—1-2, 3-4, 5-6 and 7-8—shares an internal
power supply. In current mode the power is
shared, and in voltage mode the common is shared. If
an external power supply is tied into the internal
power supply though the B pin, the signal to each
output may be distorted. It may be necessary to use a
separate external power supply for each analog
output within the pair. Each output on the PPC-2051
has a separate internal power supply so the same
external power supply may be used.
