J8/J9/J10 Power Supply Connections
J8 allows for the connection between the evaluation board and the 9V power supply provided in the
ADuC824 QuickStart Development System.
J9 and J10 allow for the connection of a typical 9V battery to the evaluation board.
J11 (DAC OpAmp Voltage Bias Input)
J11 is included as an open circuit surface mount pad on the application board. This can be used to bias the
voltage output level of the on-board DAC.
