17 The DA9052/53 provides an Analogue to Digital Converter (ADC) with 10 bits
21 the input of the ADC during the conversion.
23 The ADC is used to measure the following inputs:
26 Channel 0 VDDOUT - measurement of the system voltage
27 Channel 1 ICH - internal battery charger current measurement
28 Channel 2 TBAT - output from the battery NTC
29 Channel 3 VBAT - measurement of the battery voltage
30 Channel 4 ADC_IN4 - high impedance input (0 - 2.5V)
