Level Shifter using op-amp

We use an ADC very frequently. Input range of an ADC is normally 0 to +5V. Atmega AVRs contain typically many 10bit ADC channels (6 for atmega8 to atmega328 and 8 channels for atmega8535). The designer faces a problem when (s)he has to sense an ac signal.

DAC means digital to analog converter. The DAC circuit produces a proportional analog voltage at the output from a binary number at the input. Here I explain three different ways of implementing a DAC. वाचन सुरू ठेवा “DAC”
