5 / 66 page  ADS42B49 www.ti.com SBAS558B – DECEMBER 2012 – REVISED JANUARY 2013 ELECTRICAL CHARACTERISTICS: ADS42B49 (250 MSPS) Typical values are at +25°C, AVDD = 1.9 V, AVDD_BUF = 3.3 V, DRVDD = 1.8 V, 50% clock duty cycle, –1-dBFS differential analog input, LVDS interface, and 0-dB gain, unless otherwise noted. Minimum and maximum values are across the full temperature range: TMIN = –40°C to TMAX = +85°C, AVDD = 1.9 V, AVDD_BUF = 3.3 V, and DRVDD = 1.8 V.
