1. Typical values assume VDDA = 3.0 V, Temp = 25°C, fADCK = 1.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
2. DC potential difference.
3. This resistance is external to MCU. The analog source resistance should be kept as low as possible in order to achieve the
best results. The results in this datasheet were derived from a system which has <8 Ω analog source resistance. The RAS/
CAS time constant should be kept to <1ns.
4. In order to use the maximum ADC conversion clock frequency ADHSC bit should be set and the ADLPC should be clear.
5. In order to use the maximum ADC conversion clock frequency ADHSC bit should be set and the ADLPC should be clear.
