Electrical Characteristics (Continued)
The following specifications apply for V+ = AV+ = DV+ =
lar operation or V= −5.0 VDC for bipolar operation, and
+fCL5K.0=V5D.C0,
VREF+ = 5.000 VDC, VREF− = GND, V= GND for unipo-
MHz unless otherwise specified. Boldface limits apply
for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25˚C. (Notes 8, 9, 12)
