12-bit ADC Characteristics
Electrical data are in accordance with the following standard conditions unless otherwise specified:
Operating temperature range from -40°C to + 105°C 
Min and max data are defined as three times the standard deviation of the manufacturing process 
44.8.1 ADC Power Supply
Notes: 1. See 
.
2. In Sleep mode the ADC core, sample and hold, and internal reference operational amplifier are off.
3. In Fast Wake-up mode, only the ADC core is off. 
44.8.1.1 ADC Bias Current  
All current consumption is performed when the field IBCTL in the ADC Analog Control register (ADC_ACR) is set 
to 01.
IBCTL controls the ADC biasing current, with the nominal setting IBCTL = 01.
IBCTL = 00 is the required value for a sampling frequency below 500 kHz, and IBCTL = 01 for a sampling 
frequency between 500 kHz and 1 MHz.
