Manufacturer:ON Description:Note 12: For VIN(−) VIN(+) the digital code will be 0000 0000. Two on-chip diodes are tied to each analog input (see Functional Block Diagram) which will forward-conduct for analog input voltages one diode drop below ground or one diode drop greater than VCC supply. During testing at low VCC levels (e.g., 4.5V), high level analog inputs (e.g., 5V) can cause an input diode to conduct, especially at elevated temperatures, which will cause errors for analog inputs near full-scale. The spec allows 50 mV forward bias of either diode; this means that as long as the analog VIN does not exceed the supply voltage by more than 50 mV, the output code will be correct. Exceeding this range on an unselected channel will corrupt the reading of a selected channel. Achievement of an absolute 0 VDC to 5 VDC input voltage range will therefore require a minimum supply voltage of 4.950 VDC over temperature variations, initial tolerance and loading. |
