PQFP Pkg. Pin Name Description Pin Number Pin Number 6 44 CH0 The eight analog inputs to the Multiplexer. Active channels are selected based on the contents of bits b3–b0 of the Configuration register. Refer to section titled MUX for more details. 7 1 CH1 8 2 CH2 9 3 CH3 15 9 CH4 16 10 CH5 17 11 CH6 18 12 CH7 14 8 COM This pin is another analog input pin used as a pseudo ground when the multiplexer is configured in single-ended mode. 13 7 V REF+ Positive reference input. The operating voltage range for this input is 1V ≤ V REF+ ≤ V A+ (see Figure 3 and 4). This pin should be bypassed to AGND at least with a parallel combination of a 10 µF and a 0.1 µF (ceramic) capacitors. The capacitors should be placed as close to the part as possible. www.national.com 2 |
