Part Number:UCD3138A
Hi TI,
I have 2 question about adc mode of UCD3138A
1. In datesheet " NOTE: Even though the ADC12 sampling frequency is preset to 267 Ksps as default by setting the
ADC_SAMPLINGSEL to zero, in order to achieve the best measurement results it is
recommended to set the sampling rate to 267 Ksps by setting the ADC_SAMPLINGSEL to 6"
so do I have to configure this ADC_SAMPLINGSEL ? What will happen if I don't configure, because in default it is 267 Ksps?
2. The ADC12 control provides capability for averaging of ADC results, Set 100us to trigger adc mode in the code. If I choose 8-sample moving average, so 800us later I can get the averaging of ADC value at the beginning?
If the ADC conversion is complete, you check .ADC_INT? what is the different between ADC_INT_RAW and ADC_INT?
If I used ADC averaging, must I use .ADC_INT ?
Best Wishes
