We want to use an external reference voltage for ADS1248.
In the datasheet, it is written that the external voltage should not exceed (AVDD-AVSS)-1. Our AVDD=5V and AVSS=GND. So in this situtation; can we use a 4.096V external voltage?
Also should the REFP0 and REFN0 pins be connected to the external voltage and GND? Do we need a capacitor between REFP0 and REFN0 pins in this case? Should VREFOUT and VREFCOM pins be connected to GND when using an external voltage?
