5.8 Electrical Characteristics - AC Specifications (65 MSPS) (continued)

Maximum and minimum values are specified over the operating free-air temperature range and nominal supply voltages.

Typical values are specified at TA = 25°C, AVDD = IOVDD = 1.8 V, FS = 65 MSPS, FIN = 5 MHz, AIN = -1dBFS, Internal 1.2 V

reference , and 50% clock duty cycle, unless otherwise noted
