How to estimate the total ADC conversion time? Datum：2020-04-13
The total ADC conversion time follows the equation below:
TADC = TSMP + Tconv
Where
TADC = total conversion time
TSMP = sampling time
Tconv = conversion time = 1.625us
The sampling time follows the equation below:
where FADCAQT= Fsys
With the condition Fsys = 16MHz,
The ADC controller supports continuous conversion mode and interrupt conversion mode, and the specific calculation formula is detailed below.
1. Continuous conversion mode
The total ADC conversion time is
Thus, the ADC conversion rate is 500 kHz.
2. Interrupt conversion mode
Setting ADC converting software start trigger bit and waiting for ADC flag to be set requires about 9 cycles, as shown in the figure below.
The total ADC conversion time is
Thus, the ADC conversion rate is 390 kHz.
