Converter Characteristics (Notes 6, 7, 8, 9, 19) (Continued)
The following specifications apply to the LM12454, LM12458, and LM12H458 for V
A+ = VD+ = 5V, VREF+ = 5V, VREF− = 0V,
12-bit + sign conversion mode, f
CLK = 8.0 MHz (LM12H458) or fCLK = 5.0 MHz (LM12454/8), RS = 25Ω, source impedance for
V
REF+ and VREF− ≤ 25Ω, fully-differential input with fixed 2.5V common-mode voltage, and minimum acquisition time unless
otherwise specified. Boldface limits apply for T
A = TJ = TMIN to TMAX; all other limits TA = TJ = 25˚C.
