* These parameters are characterized but not tested. † Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested. Note: Settling time measured while DACR[7:0] transitions from `‘b00000000` to `‘b11111111`. This parameter only applies to the buffered DAC1 module, and does not apply to the unbuffered DAC2.
