Figure 16. Illustrative Temperature Profile
This may be expressed analytically as the following:
where
•
VHYS = Thermal hysteresis expressed in ppm
•
VREF = Nominal preset output voltage
•
VREF1 = VREF before temperature fluctuation
•
VREF2 = VREF after temperature fluctuation
(2)
The LM4128 features a low thermal hysteresis of 190 µV from -40°C to 125°C.
TEMPERATURE COEFFICIENT
Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range.
This deviation over temperature may be illustrated as shown in Figure 17.
