The digital output load during test is not to exceed an ac load of 10 pF or a dc current of ±40 µA. 3 Digital supply current based on VDD = 3.0 V output drive with < 10 pF loading under dynamic test conditions. 4 Power dissipation measured under the following conditions: fS = 100 MSPS, analog input is –0.7 dBFS, both channels in operation. 5 Standby dissipation calculated with Encode clock in operation. 6 SNR/harmonics based on an analog input voltage of –0.7 dBFS referenced to a 1.024 V full-scale input range.
EXPLANATION OF TEST LEVELS Level Description
I 100% production tested. II 100% production tested at 25°C and sample tested at specified temperatures. III Sample tested only. IV Parameter is guaranteed by design and characterization testing. V Parameter is a typical value only. VI 100% production tested at 25°C; guaranteed by design and characterization testing for industrial temperature range; 100% production tested at temperature extremes for military devices. Rev.
