Binary Weighted DAC Explained by diether.gozum is a document available to read on EtoBox.
A binary weighted digital-to-analog converter (DAC) uses a summing amplifier circuit with resistor values that are weighted in powers of two to convert a digital binary number into a proportional analog output voltage. An operational amplifier is used as a summing inverting amplifier, with inputs weighted by resistor values of 1k, 2k, 4k, and 8k Ohms, representing the 20, 21, 22, 23 bit weights. This creates a simple 4-bit DAC with an output resolution of 0.625 volts that converts each binary input combinat
