The current value is then summed by an operational amplifier and converted to a voltage value.ĭepending on the bit weighted network, different types of DACs can be formed, such as weighted resistor network DAC, R-2R inverted T-resistor network DAC, and single-value current network DAC.

The digital-to-analog converter is composed of a digital register, an analog electronic switch, a decoding network, a summing operational amplifier, and a reference voltage source (or constant current source). An analog-to-digital converter, or A/D converter, or ADC, is a device that converts a continuous analog signal into a discrete digital signal. Analog-to-digital converters generally require the use of digital-to-analog converters. A D/A converter basically consists of four parts, namely a weighted resistor network, an operational amplifier, a reference power supply, and an analog switch. A digital-to-analog converter, also known as a D/A converter or DAC for short, is a device that converts a digital quantity into an analog quantity.
