deasserted, DACSn is cleared to 0.
Two circuits of digital-to-analog (D/A) converters are provided. These D/A converters are of voltage output type
The conversion method is of R-2R resistor ladder type. By writing a value to be output to an 8-bit D/A conversion
Because the output impedance is high, no current can be extracted from the output. If the impedance of the load
The ANOn pin goes into a high-impedance state while the RESET signal is low. When the RESET signal is
