Refer to Table 57 for analog valid input range and input buffer range characteristics for each ADC Channel

Table 3. Static Electrical Characteristics

TA = -40 to 85 °C, VPWR = 3.0 to 4.4 V, in gathering these parametrics, Freescale used the external components described in

the Hardware Design Considerations section of this document, over the full load current range, unless otherwise noted. Typical

values are characterized at VPWR = 3.6 V and 25 °C.
