The article presents information on 32-bit Digital-to-Analog converters (DAC). The basis of the DAC's 32-bit resolution is the summing of two 16-bit PWM signals by analog switches and precision resistor network. A DAC with extremely good resolution, monotonicity, accuracy, and resolution such as 32-bit DAC are required in some applications, such as in analog-to-digital-converter (ADC) testing and calibration. A DAC circuit is also offered in the article.
