1. Guaranteed by design, unless otherwise specified.

2. The temperature range is limited to 0 °C-125 °C when VDDA is below 2 V

3. Guaranteed by characterization results.

4. Mostly I/O leakage, when used in analog mode. Refer to Ilkg parameter in Table 59: I/O static characteristics.

5. R2 is the internal resistance between OPAMP output and OPAMP inverting input. R1 is the internal resistance between

OPAMP inverting input and ground. The PGA gain =1+R2/R1
