DS07-13707-5E
14. 8-bit D/A Converter
The 8-bit D/A converter performs R-2R D/A conversion with 8-bit resolution.
Two D/A converter channels with independent analog outputs are provided.
D/A converter functions
D/A converter theoretical output voltage
Note : DVCC voltage : D/A converter reference voltage. This must not exceed VCC.
Also, always ensure that DVSS is equipotential to VSS.
Function
D/A conversion time
The settling time is 12.5
s. This is independent of the machine clock.
Conversion method
R-2R conversion
Resolution
8-bit
Analog output pins
Two output pins are provided. Both pins can be used simultaneously.
Interrupts
None
D/A conversion trigger
Set the digital value in the D/A data register (DADR) , then enable D/A output in the
D/A control register (DACR) to start analog output from the D/A output pin.
EI2OS support
Not supported by the extended intelligent I/O service (EI2OS) .
D/A Data Register Setting
