NOTES

An ‘‘LSB’’ as used here has a value of approximately 20 mV (See Embedded Microcontrollers and Processors Handbook

for AD 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
