Note 12. AIN2LP, AIN2LN, AIN2RP and AIN2RN pins.
Note 13. ADC2VL/R bit = “0”. Input full-scale voltage is propotional to AVDD (0.7 x AVDD).
Note 14. ADC2VL/R bit = “0”. Input full-scale voltage is propotional to AVDD (0.86 x AVDD).
Note 15. AIN3L, AIN3R, AIN4L, AIN4R, AIN5L and AIN5R pins.
Note 16. Common mode rejection ratio is applied 1kHz and 100mVpp sine waves to both
Pseudo-differential input and Pseudo-differential ground input pins. It is defined as a
reference value when appling 100mVpp sine wave to the Pseudo-differential input.
