NOTES:
1. An LSB, as used here, has a value of approximately 20 mV.
2. Most parts will need these values at 25°C, but they are not tested or guaranteed.
3. DC to 100 KHz.
4. Multiplexer break-before-make guaranteed.
5. Resistance from device pin, through internal multiplexer, to sample capacitor.
6. Applying voltage beyond these specifications will degrade the accuracy of other channels being con-
verted.
7. All conversions were performed with processor in idle mode.
8. 100 mV < V_IN < V_REF – 100 mV.
