NOTES

1. The switching threshold is typically V DD/2 for –1 models

and V DD/6 for –2 models.

The logic input must never exceed V DD/3 (or –2 models.

2. Using internal feedback resistor.

3. Using the internal Ffeedback with nulled external

amplifier in a constant 25ºC ambient. (Offset doubles every 10ºC).

4. Best straight line method of test.

5. The DA C9331-14 Series is designed to be used only in those applications

where the current output is virtual ground: i.e., the summing junction

of an op amp in the inverting mode. The internal feedback resistor

(R feedback) must be used to achieve temperature tracking.

See A PPLICA TIONS INFORM A TION for recommended

circuit configurations.

6. The power supply voltage must not exceed +10V for the

–1 versions or +15.5V for the –2 versions.
