NOTES
1
Gain error and gain temperature coefficient are based on the ADC only (with a fixed –2.5 V external reference).
2
t
V
and t
PD
are measured from the threshold crossing of the ENCODE input to the 50% levels of the digital outputs. The output ac load during test is 10 pF.
3
Power dissipation is measured under the following conditions: f
S
100 MSPS, analog input is –1 dBfs at 10.3 MHz. Power dissipation does not include the current of
the external ECL pull-down resistors that set the current in the ECL output followers.
4
A change in input offset voltage with respect to a change in V
EE
.
5
SNR/harmonics based on an analog input voltage of –1.0 dBfs referenced to a 1.024 V full-scale input range.
