DYNAMIC ACCURACY The
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations 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.
