NOTES:
4. Full scale range (FSR) is 10V (reference adjusted).
5. Assume all leads are soldered or welded to printed circuit board.
6. “J” and “K” versions not production tested. Guaranteed by Integral Linearity Test.
7. Typical values are not tested, for reference only.
8. Not production tested. Guaranteed by design.
AC Electrical Specifications Test Conditions V+ = +5V, V- = -5V, TA = 25oC, fCLK = 500kHz, unless otherwise noted. Data
derived from extensive characterization testing. Parameters are not production tested
