hi,
CYW20819 is a single-ended switched-capacitor sigma-delta ADC with 12 bits for Audio* measurements and 10 bits for DC measurements.
The application need a 11 or 12 bit ADC for DC measurements, don't need hight conversion rate (10KHZ), is there a way to get 12 bit general ADC?
Regards,
Nicole

Hi,
Q) The application need a 11 or 12 bit ADC for DC measurements, don't need hight conversion rate (10KHZ), is there a way to get 12 bit general ADC?
A) You can't configure it to 12 bit ADC. You may try using API wiced_hal_adc_read_raw_sample ( 20819-A1_Bluetooth\include\20819\hal\wiced_hal_adc.h ) . It will give 16 bit raw value directly from the register. You can take the 12 bit value from that and can use in application as per your requirement.
