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 the pin current is limited to
g
2 mA.
6. Applying voltages beyond these specifications will degrade the accuracy of other channels being converted.
7. All conversions performed with processor in IDLE mode.
