NOTES:

An ``LSB'' as used here has a value of approximately 20 mV. (See Embedded Microcontrollers and Processors Handbook

for A/D glossary of terms).

1. These values are expected for most parts at 25 C but are not tested or guaranteed.

2. DC to 100 KHz.

3. Multiplexer Break-Before-Make is guaranteed.

4. Resistance from device pin, through internal MUX, to sample capacitor.

6. Applying voltages beyond these specifications will degrade the accuracy of other channels being converted.

7. All conversions performed with processor in IDLE mode.
