5 / 29 page Electrical Characteristics (Continued) The following specifications apply for V + =AV+ =DV+ = +5.0 V DC,VREF+ = 2.5 VDC,VREF− = GND, VIN− = 2.5V for Signed Characteristics, V IN− = GND for Unsigned Characteristics and fCLK = 2.5 MHz unless otherwise specified. Boldface limits ap- ply for T A =TJ =TMIN to TMAX; all other limits TA =TJ = +25˚C.
