(4)

Output noise voltage is proportional to VOUT. VN for other voltage option is calculated using (VN(1.8 V) / 1.8) × VOUT.

VN (2.5 V) = (36 μVPP / 1.8) × 2.5 = 46 μVPP.

(5)

Thermal hysteresis is defined as the change in 25°C output voltage before and after exposing the device to temperature extremes.

(6)

Long term stability is change in VREF at 25°C measured continuously during 1000 hours.
