5 / 61 page  ADS4128 www.ti.com SBAS578 – MAY 2012 ELECTRICAL CHARACTERISTICS Typical values are at +25°C, AVDD = 1.8 V, DRVDD = 1.8 V, 50% clock duty cycle, –1-dBFS differential analog input, 1-dB gain, and DDR LVDS interface, unless otherwise noted. Minimum and maximum values are across the full temperature range: TMIN = –40°C to TMAX = +85°C, AVDD = 1.8 V, and DRVDD = 1.8 V. Note that after reset, the device is in 0-dB gain mode.
