NOTES:

* Same as A Models.

1. The specified values are without external trim.

2. The temperature coefficient (TC) is determined by the box method using the following formula:

T.C. =

VMAX – VMIN

VNOMINAL x (TMAX – TMIN)

x 106

4. The tracking error is the deviation between the positive and negative output over the operating

temp. range.

5. The specified values are unloaded.
