Abstract. The paper investigates the possibility of using digital-to-analog converters as a generator of linearly varying voltage. The analysis of the digital-to-analog converter model is carried out. The methodology is developed and the results of the evaluation of the main characteristics of the digital-to-analog converter are presented. The possibilities of increasing the accuracy with the help of the presented model of the developed generator of linearly varying voltage are investigated.
