Note:

Fos is oversampling frequency. When in Hybrid mode, Fos is 1/ (the sum of the oversampling periods of each analog channel

assigned to the scan group).

Note 1. Differential input voltage is (AINP - AINN)

● AINP is input voltage of ANx, and VREFL0 ≤ AINP ≤ VREFH0.

● AINN is input voltage of ANy, and VREFL0 ≤ AINN ≤ VREFH0.

(x = 2i, y = 2i +1, i = 0, 1, 2… (any integer))

Note 2. See Figure 2.50 and Figure 2.51.

Note 3. Value per channel.
