ELECTRICAL CHARACTERISTICS: General

Typical values are at TA = +25°C, AVDD = 1.8 V, LVDD = 1.8 V, 50% clock duty cycle, 100 MSPS, two-wire LVDS interface,

and –1-dBFS differential analog input, unless otherwise noted.

Minimum and maximum values are across the full temperature range of TMIN = –40°C to TMAX = +85°C, AVDD = 1.8 V, and

LVDD = 1.8 V.
