1 Temperature range TMIN to TMAX: 40°C to +85°C at 50 MHz and 140 MHz, 0°C to 70°C at 240 MHz and 330 MHz.
2 These maximum/minimum specifications are guaranteed by characterization to be over the 3.0 V to 3.6 V range.
3 Gain error = {(Measured (FSC)/Ideal (FSC) 1) × 100}, where Ideal = 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.
