1 These numbers are not production tested but are guaranteed by design and/or characterization data at production release.

2 Enabling the input buffer changes the ADC input characteristics as described in this subsection.

3 The data in this section also applies for a load of RL = 1 kΩ and CL = 100 pF to GND but only for 0 V to 2.5 V. However, this is not production tested.

4 DAC linearity is calculated using a reduced code range of 100 to 3900.

5 DAC gain error is calculated using a reduced code range of 100 to an internal 2.5 V VREF.

6 Due to self heating, internal temperature measurements cannot be used to predict external temperatures. This value is only relevant after user calibration and only for

internal and external conditions identical to those at calibration.

7 The average current from all GPIO pins must not exceed 3 mA per pin.

8 Power figures exclude any load currents to external circuits.
