sinc_adc
Overview
The sinc adc example shows how to use SINC driver to configure SINC module as single conversion mode to convert an external ADC sigma-delta modulator bitstream to a data stream. For this example, the over sample ratio is set as 128, the order is 3, and the SINC result data is signed. Theoretically, When ADCin = 0V, ADC output 50% duty of MBIT, sinc result is 0x0(If unsigned mode, sinc result is 128^3/2 = 0x10_0000); when ADCin = + maximum input voltage, ADC output always output 1(100% duty), SINC output is 128^3 = 0x20_0000. when ADCin = - maximum input voltage, ADC output always output 0(0% duty), SINC output is -128^3 = 0xE0_0000(If unsigned mode, sinc result is 0x0). For ADCin between -maximum input voltage and +maximum input voltage, the SINC result is ADCin/maximum * 0x20_0000.
