SLAS760C – MAY 2011 – REVISED JANUARY 2013
ELECTRICAL CHARACTERISTICS DYNAMIC PERFORMANCE – 16-BIT ADC
Typical values are at 25°C, AVDD = 3.3V, LVDD = 1.8 V, 50% clock duty cycle, –1-dBFS differential analog input (unless
otherwise noted).
MIN and MAX values are across the full temperature range T_MIN = –40°C to T_MAX = 85°C, AVDD = 3.3 V, LVDD = 1.8 V
