Part Number: ADS7253
I could get one sample value(eg, current) with one request, as general application. Now I want to get two sample value(eg, current1, current 2) with one request(send SPI msg only once), so I could caculate the current = (current1 + current2)/2 which gets rid of noise and has higher accurate. I am not sure if ADS7253 has this function, and if yes, how to use it ?
Thank you for your post.
What you are describing is the averaging of back-to-back samples in order to reduce the noise in the measurement. A SAR ADC only performs a single conversion at a time. In order to average samples, you must collect multiple samples and average the results in post-processing.
