Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png ControlPins
Allows Shutdown (SHDN) and Latch (LDAC) pins to be controlled directly if enabled. 
Fc9-bool-icon.png - BOOL Shutdown
0 = Shutdown Device, 1 = Device Active 
Fc9-bool-icon.png - BOOL Latch
0 = Data output driven from DAC register, 1 = Data output locked 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png Disable
Disables the DAC output. 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png Enable
