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.
5. These values may be exceeded if pin current is limited to g2 mA.
6. Applying voltages beyond these specifications will degrade the accuracy of all channels being converted.
7. All conversions performed with processor in IDLE mode.
