An ‘‘LSB’’ as used here has a value of approximately 5 mV
NOTES
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 Applying voltages beyond these specifications will degrade the accuracy of other channels being converted
6 All conversions performed with processor in IDLE mode
