Part Number:ADS1248
Hi,
I would like to ask you a simple question about the calibration.
The data sheet of ADS1248 describes about calibration as below. (40page)
According to this description, we should or must do calibration when we use ADS1248.
That is to say, before the start of ADC, we have to do calibration, every ADC.
Is this a correct way to use ADS1248?
On the other hand, there are some delta-sgima ADCs without calibration, for example ADS1251.
I suppose ADS1251 is easier to use than ADS1248.
Will you tell me the reason why ADS1251 does not have calibration?
It has something auto-calibration circuits??
Sorry for my very basic question.
Best Regards,
