7 / 43 page DC Characteristics (Notes 6, 7, 8, 19) The following specifications apply to the LM12454, LM12458, and LM12H458 for V A+ = VD+ = 5V, VREF+ = 5V, VREF− = 0V, f CLK = 8.0 MHz (LM12H454/8) or fCLK = 5.0 MHz (LM12458), and minimum acquisition time unless otherwise specified. Bold- face limits apply for T A = TJ = TMIN to TMAX; all other limits TA = TJ = 25˚C.
