6.5 Electrical Characteristics - Power Consumption

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, FIN = 5MHz, AIN = -1dBFS, Internal 1.2 V reference, 5 pF

output load, and 50% clock duty cycle, unless otherwise noted
