The C8051F060/1/2/3 devices include two on-chip 12-bit voltage-mode Digital-to-Analog Converters
(DACs). Each DAC has an output swing of 0 V to (VREF-1LSB) for a corresponding input code range of
0x000 to 0xFFF. The DACs may be enabled/disabled via their corresponding control registers, DAC0CN
and DAC1CN. While disabled, the DAC output is maintained in a high-impedance state, and the DAC sup-
ply current falls to 1 µA or less. The voltage reference for each DAC is supplied at the VREFD pin
(C8051F060/2 devices) or the VREF2 pin (C8051F061/3 devices). See
(C8051F060/2)” on page 111
information on configuring the voltage reference for the DACs. Note that the BIASE bit described in the
voltage reference sections must be set to ‘1’ to use the DACs.
