A to D CHARACTERISTICS
The A D converter is ratiometric so absolute accuracy is dependent on the accuracy and stability of V_REF

NOTES
An ‘‘LSB’’ as used here has a value of approxiimately 5 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 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
