本文设计了一个数字输入和模拟输出呈斜锯齿波变化且位数可在７、１１、１５、１９位４种结果中选择的双ＤＡＣ电路。它设计在一单片机内，作掌型电脑的声音控制。
This text has designed a double DAC circuit that the digital input and analog output are changed in the intersection of ramping and the intersection of wave and the intersection of tooth and the intersection of 7 and the intersection of puncture and the intersection of 15,19 and 4 kinds of result. It is designed in a single-chip computer, for the palm-type computer sound control.
