reference voltage
There is a built-in 4-V reference. If the internal reference is used, REFP is internally set to 4-V and REFM is set
to 0-V. The external reference can be applied to the reference-input pins (REFP and REFM) if programmed (see
Table 2). The REFM pin should connect to analog ground. REFP can be 3-V to 5-V. Install decoupling capacitors
(10
F in parallel with 0.1 F) between REFP and REFM. Install compensation capacitors (10 F in parallel with
0.1
F for internal reference, 0.1 F only for external reference) between BGAP and AGND.
