__LL_DAC_DIGITAL_SCALE macro

Helper macro to define the DAC conversion data full-scale digital value corresponding to the selected DAC resolution.

Syntax

#define __LL_DAC_DIGITAL_SCALE(__DAC_RESOLUTION__) \ ((0x00000FFFUL) >> ((__DAC_RESOLUTION__) << 1UL))

This parameter can be one of the following values: @arg LL_DAC_RESOLUTION_12B @arg LL_DAC_RESOLUTION_8B

ADC conversion data equivalent voltage value (unit: mVolt)

DAC conversion data full-scale corresponds to voltage range determined by analog voltage references Vref+ and Vref- (refer to reference manual).

__LL_DAC_DIGITAL_SCALE is referenced by 3 libraries and example projects.
