CN10396470A Low-power consumption level multi.
For example an bit DAC that generates a maximum output voltage of 5 volts has a step size or resolution of 5V 2 195 mV Sometimes the resolution is stated in the percentage value For the bit DAC the percent resolution is 1 2 x 100 039.

General Description The Voltage Reference Vref component allows you to provide a stable precision reference voltage for the analog resources in your design Each component instance represents a physical analog reference source in the PSoC device.
The reference voltage to the analog-to-digital ADC and digital- to-analog DAC converters can be.
The reference voltage 256 V is represented by the maximum conversion value 1024 so the scaling factor is 1024256 400 bits per volt The input is therefore divided by this factor to obtain a display in volts.

The adc hard block samples from small transistors can best possible to digital test. Vref is the reference voltage if the analog value at the input becomes greater. Same 3-bit ADC circuit diagram but with component values reference voltage and. Where M is the ADC's resolution in bits and EFSR is the full scale voltage. The ADC of the AVR maxEmbedded.
Relating ADC Value to Voltage The ADC reports a ratiometric value This means that the ADC assumes 5V is 1023 and anything less than 5V will be a ratio between 5V and 1023 If your system is 33V you simply change 5V out with 33V in the equation.
