Maxim Integrated 

Dual, 80Msps, 12-Bit, IF/Baseband ADC

ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.3V, OVDD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), CL ≈ 10pF at digital outputs, AIN = -0.5dBFS (differen-

tial), DIFFCLK/SECLK = OVDD, PD = GND, SHREF = GND, DIV2 = GND, DIV4 = GND, G/T = GND, fCLK = 80MHz, TA = -40°C to

+85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
