1.10. 12-bit Digital to Analog Converters
The C8051F060/1/2/3 MCUs 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 C8051F060/2
devices or via the VREF2 pin on C8051F061/3 devices, which is shared with ADC2. The DACs are espe-
cially useful as references for the comparators or offsets for the differential inputs of the ADCs.
