NOTES:

* Same as A/J Models.

1. The temp. reference TC is 2.1 mV/ 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.
