T Specifications same as grade to the left.

NOTE: (1) If VSS = 0V, the specification applies at code 0021H and above, due to possible negative zero scale error.

SPECIFICATIONS (Single Supply)

At TA = TMIN to TMAX, VCC = +15V, VDD = +5V, VSS = GND, VREFH = +10V, and VREFL = +50mV, unless otherwise noted.
