C.2 Power Supply
The OP6800 requires an unregulated +RAW power input of 9 V to 36 V DC, which can be
supplied from the Demonstration Board through the ribbon cable connection. The OP6800
has its own switching voltage regulator.
Figure C-2 shows the distribution of the +RAW input power to the OP6800 through the
Demonstration Board. The reference grounds on the OP6800, GND, and on the Demon-
stration Board, 0 V, are tied together at one connection point only to avoid creating a
ground loop, which could lead to considerable electromagnetic interference.
