Rs represents a possible external series resistor between the voltage source and the ADIN input. 7. At room temperature. 8. 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. Characteristic Symbol Min Typ Max Unit |
