AC CHARACTERISTICS

ADS5273

SBAS305D – JANUARY 2004 – REVISED JANUARY 2009 .............................................................................................................................................. www.ti.com

TMIN = –40°C and TMAX = +85°C. Typical values are at TA = +25°C, sampling rate = 70MSPS, 50% clock duty cycle,

AVDD = 3.3V, LVDD = 3.3V, –1dBFS, ISET = 56.2kΩ, internal voltage reference, and LVDS buffer current at 3.5mA per

channel, unless otherwise noted. All voltages are applicable after the device has been reset.
