1.10. 12-bit Digital to Analog Converters
The C8051F12x devices have two integrated 12-bit Digital to Analog Converters (DACs). The MCU data
and control interface to each DAC is via the Special Function Registers. The MCU can place either or both
of the DACs in a low power shutdown mode.
The DACs are voltage output mode and include a flexible output scheduling mechanism. This scheduling
mechanism allows DAC output updates to be forced by a software write or scheduled on a Timer 2, 3, or 4
overflow. The DAC voltage reference is supplied from the dedicated VREFD input pin on the 100-pin TQFP
devices or via the internal Voltage reference on the 64-pin TQFP devices. The DACs are especially useful
as references for the comparators or offsets for the differential inputs of the ADCs.
