摘要：
The present invention relates to a digital-to-analog converter having a plurality of inputs (B0,B1,B2,B3) for digital signals, and an output (OUT) for an analog signal, and comprising a charge integration circuit (INT) having an input and an output coupled to the converter output, and a plurality of floating gate MOS transistors (M01, M11,M21,M31) corresponding to the plurality of converter inputs, having their source and drain terminals coupled all together and to the input (ND) of the integration circuit (INT), and having control terminals coupleable, under control from the inputs of the plurality, to different references (VCC,GND) of potential having selected fixed values.
