AN-695 APPLICATION NOTE
... VREF is the reference voltage. When taken from the ADN8831, VREF = 2.5 V. Alternatively, measuring the voltage difference between the LFB and SFB pins also results in the voltage across the TEC (VTEC). Typically, the LFB pin connects to the positive terminal of the TEC, and the SFB pin connects to t ...
