The 1V0 is a bandgap voltage reference which is able to provide custom temperature independent voltage in range from 0 to 1.175V. More outputs are supported with step of 50mV available at VREF<1:23> and voltage at VREF<24> is equal to 1.175V.
The 1V0 is a standard implementation using NPN bipolar devices in Brokaw bandgap structure. The deep-nwell option is required. The block also provides Proportional to Absolute Temperature (PTAT) current reference.
The reference contains slope and absolute voltage trimming which allows to obtain accuracy down to 0.2% at ambient temperature and 0.3% over temperature range if two temperature point trimming procedure is followed (0 and 70 degrees).
