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.
