ABSTRACT:
A digital-to-analog converter (DAC) includes an R-2R ladder network, switches, and an operation amplifier (OP) with a feedback resistance, for providing an analog voltage in a positive polarity and a negative polarity. Each of the switches is switched between a connection to the OP and the reference voltage.
