1. To 1% of set value with 50pf load connected to trim pins.
2. Total time required to update a single TRIMx output value by setting the associated DAC through the I 2 C port.
3. This is the total resultant error in the trimmed power supply output voltage referred to any DAC code due to the DAC’s INL, DNL, gain, out-
put impedance, offset error and bipolar offset error across the industrial temperature range and the ispPAC-POWR6AT6 operating V CCA
and V CCD ranges.
