B.1 Power Supplies
Power is supplied to the OP6800 via pins 20 and 21 of header J1, which is connected by a
ribbon cable to either the Demonstration Board or to your system. The OP6800 is pro-
tected against reverse polarity by a diode at D6 as shown in Figure B-1.
The input voltage range is from 9 V to 36 V. A switching power regulator is used to pro-
vide a Vcc of +5 V for the OP6800 logic circuits. Vcc is not accessible to the user.
User’s Manual
Appendix B describes the power circuitry provided on the
OP6800.
NOTE: In addition to supplying +RAW to the OP6800 switching power regulator, the
Demonstration Board has its own independent linear power regulator to supply the
electronics in the demonstration area of the Demonstration Board. See Appendix C for
more information.
