These parameters are for design guidance only and are not tested. Note 1: By design, the Oscillator Start-up Timer (OST) counts the first 1024 cycles, independent of frequency. 2: To ensure these voltage tolerances, VDD and VSS must be capacitively decoupled as close to the device as possible. 0.1 F and 0.01 F values in parallel are recommended. Operating Conditions (unless otherwise stated) VDD = 3.0V, TA = 25°C Param No. Sym. Characteristic Min. Typ† Max.

These parameters are for design guidance only and are not tested. Note 1: Total Absolute Error is the sum of the offset, gain and integral non-linearity (INL) errors. 2: The ADC conversion result never decreases with an increase in the input and has no missing codes. |
