Be careful during testing at low VCC levels (4.5V), as high level reference or analog inputs (5V) can cause this input diode to conduct, especially at elevated temperatures, and cause errors for inputs near full scale. This spec allows 50mV forward bias of either diode. This means that as long as the reference or analog input does not exceed the supply voltage by more than 50mV, the output code will be correct. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply voltage of 4.950V over initial tolerance, temperature variations and loading. Note 8: Channel leakage current is measured after the channel selection. Note 9: Increased leakage currents at elevated temperatures cause the S/ H to droop, therefore it is recommended that fCLK ≥125kHz at 125°C, fCLK ≥ 31kHz at 85°C, and fCLK ≥ 3kHz at 25°C. The q denotes specifications which apply over the operating temperature range; all other limits and typicals TA = 25°C. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: All voltage values are with respect to ground (unless otherwise noted). Note 3: VCC = 5V, VREF = 5V, CLK = 1.0MHz unless otherwise specified. Note 4: One LSB is equal to VREF divided by 4096. For example, when VREF = 5V, 1LSB = 5V/4096 = 1.22mV. Note 5: Linearity error is specified between the actual end points of the A/D transfer curve. The deviation is measured from the center of the quantization band. Note 6: Recommended operating conditions. Note 7: Two on-chip diodes are tied to each reference and analog input which will conduct for reference or analog input voltages one diode drop |
