D/A Converter
Two circuits of digital-to-analog (D/A) converters are provided. These D/A converters are of voltage output type
and have a resolution of 8 bits.
The conversion method is of R-2R resistor ladder type. By writing a value to be output to an 8-bit D/A conversion
value setting register (DACSn: n = 0 or 1), an analog value is output to the ANOn (n = 0 or 1) pin. The output voltage
range is determined by the voltage applied across the AV
REF2
and AV
REF3
pins.
Because the output impedance is high, no current can be extracted from the output. If the impedance of the load
is low, insert a buffer amplifier between the load and output pin.
The ANOn pin goes into a high-impedance state while the RESET signal is low. When the RESET signal is
deasserted, DACSn is cleared to 0.
