Hello E2E Experts,
Good day.
Hello,
When averaging is enabled, channel 1's samples are first averaged, then channel 2, and so on. In autonomous mode, this applies for whichever channels are enabled in the AUTO_SEQ_CH_SEL register. So you cannot choose to oversample and average one channel while not also oversampling and averaging the others.
Your averaging factor will be equal to your oversampling rate. If you are oversampling by 4x (setting OSR_CFG register to 10b), you will average by 4x. If you wish to sample your signal at 8 ksps, and set an OSR of 4x, you are effectively sampling at 32 ksps, but your data rate will remain at 8 ksps. You won't "see" that you are oversampling when you are reading your data, but the data will be the average of multiple samples. I hope this is enough to help you make a determination.
You can share the same SPI port with multiple ADS7038 devices as SDO is in high-impedance mode when CS is high.
Best,
Joel
