Abstract
In this paper, the circuit implementation principle, circuit design characteristic and process technology characteristic for a 12-bit voltage output D/A converter with internal reference were described. By using analog unit circuits such as the R-2R resistance switch network optimized in design, the temperature compensation Zener reference voltage, and the BiCMOS output operational amplifier with JFET input, combined with SISC" p-well 3 um LC2MOS process technology, a 12-bit D/A converter was developed. The converter features high conversion resolution, small linear and differential error, low power consumption, fast conversion speed, ease of use, etc.
