STM32 DAC Tutorial - Example HAL Code & Analog Signal ...

Jun 30, 2020· STM32 DAC Calibration. The transfer function for an N-bit digital-to-analog converter (DAC) is: VOUT = ( (D/2N-1) x G x Vref) + Vos. Where VOUT is the analog output, D is the digital input, G is the gain, Vref is the nominal fullscale voltage, and Vos is the offset voltage. For an ideal DAC channel, G = 1 and Vos = 0.
