NOTES:
1. The internal buffer operational amplifier and the accuracy specifications require an external capacitor. All INL and DNL tests uses
two capacitors between pins VREF+ and AVSS and VREF/VeREF and AVSS: 10 F tantalum and 100 nF ceramic.
2. The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB. The settling time depends on the external
capacitive load.
