DYNAMIC ACCURACY The l denotes the specications which apply over the full operating temperature range,
otherwise specications are at TA = 25°C. With internal reference, VDD = 3V. Single-ended signal drive CH0+/CH1+ with
CHO–/CH1– = 1.5V DC. Differential signals drive both inputs of each channel with VCM = 1.5V DC.
