1 Temperature range TMIN to TMAX: −55°C to +105°C.

2 These maximum/minimum specifications are guaranteed by characterization over the 3.0 V to 3.6 V range.

3 Gain error = {(Measured (FSC)/Ideal (FSC) − 1) × 100}, where Ideal (FSC) = VREF/RSET × K × (0x3FFH) and K = 7.9896.

4 Digital supply is measured with a continuous clock that has data input corresponding to a ramp pattern and with an input level at 0 V and VDD.
