1. The temp. reference TC is 2.1mV/ ºC
2. The specified values are without external trim.
3. The temperature coefficient is determined by the box method using the following formula:
T.C. =
VMAX – VMIN
VNOMINAL x (TMAX – TMIN)
x 106
4. The specified values are without the external noise reduction capacitor.
5. The specified values are unloaded.
