DC and Logic 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, 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− ≤ 25Ω, 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.

Timing specifications are tested at the TTL logic levels, VIL = 0.4V for a falling edge and VIH = 2.4V for a rising edge. TRI-STATE output

voltage is forced to 1.4V.
