AC Electrical Characteristics (continued)

The following specifications apply for V

+ = V

A+ = VD+ = +5.0 VDC, VREF+ = +4.096 VDC, VREF− = 0 VDC, 12-bit + sign

conversion mode, tr = tf = 3 ns, fCK = fSK = 8 MHz for the ADC12H030, ADC12H032, ADC12H034 and ADC12H038, fCK = fSK

= 5 MHz for the ADC12030, ADC12032, ADC12034 and ADC12038, RS = 25Ω, source impedance for VREF+ and VREF− ≤

25

Ω, fully-differential input with fixed 2.048V common-mode voltage, and 10(tCK) acquisition time unless otherwise specified.

Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C.
