Specification
Input voltage range (for driving ADC
over its full range)
Gain error
Input referred offset voltage
Integral non-linearity (INL)

ENOB
All 3.3 V supplies are tied together and varied from 3.0 V to 3.6 V. 1.5 V supplies are held constant.
Analog-to-Digital Converter (ADC)
Unless otherwise noted, ADC direct input performance is specified at 25°C with nominal power supply
voltages, with the output measured using the external voltage reference with the internal ADC in 12-bit
mode and 500 KHz sampling frequency, after trimming and digital compensation.
