*1) Error between the I/O curve and the ideal line connecting the output voltage for the 02 setting and the
output voltage for the FF setting.
Unless otherwise specified, the following apply: AVDD = 2.6 to 3.3V, VSS = 0V, AVDD ≥ VIN, VREF =
0V to AVDD, Ta = -40°C to +85°C
DACREF shows an internal setting level of DAC reference voltage.
