WebMay 6, 2024 · I used DAC levels from 20 to 4075 to avoid zero offset errors at low voltages and DAC buffer problems at high voltages. Each series of measurements has 4056 data points. This is a voltage range of about 0.023 to 4.972 volts. I calibrated the Arduino ADC for each series of measurements with a linear fit of the form. v = a + b*adcValue WebOct 8, 2024 · The ESP32 offers two DAC outputs (on GPIO25 and GPIO26) with 8-bit resolution, but the ADC is 12-bit resolution, so there will be some loss due to interpolation between 8-bit to 12-bit, but it is not significant compare with the noise level of ESP32 (more on that later). ... Non-linearity is not the only problem of ESP32 ADCs, the reading from ... Webunder test. In the case of DAC testing, the digitizer in the DVM must be at least 10 times more linear than the DAC under test. If the INL of the DAC is at the +/-2 LSB level, then the digitizer’s non-linearity must be in the range of +/-0.2 LSB. This stringent requirement on the linearity means that a highly solidworks mold base library
