Figure

26 –Internal voltage of the ADC vs. applied voltage on CURR1,2 or CURR6

Operating conditions: VBAT>=3.3V, TJUNC >= -20

°C (one curve with charge pump operating in 1:2 mode ‘on’ and

one curve with charge pump in 1:1 mode ‘off’).

Above curve represent the worst case and therefore are guaranteed by design under the above operating

conditions (ADC input range for CURR1,2,6 is between 0V and 1.5V).
