t
V
and t
PD
are measured from the 1.5 V level of the Encode input to the 10%/90% levels of the digital outputs swing. 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 V
DD
= 3.0 V output drive with < 10 pF loading under dynamic test conditions.
4
Power dissipation measured under the following conditions: f
S
= 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.
