NOTES
1
No Missing Codes across industrial temperature range guaranteed for -40 MSPS, -65 MSPS, and -80 MSPS grades. No missing codes at room temperature guaran-
teed for -105 grade.
2
Gain error and gain temperature coefficients are based on the ADC only (with a fixed 1.25 V external reference) -65 Grade in 2 V p-p range, -40, -85, -105 Grades in
1 V p-p range.
3
(AIN –

) =
±
0.5 V in 1 V range (full scale), (AIN –
AIN
) =
±
1 V in 2 V range (full scale).
4
AC Power Dissipation measured with rated encode and a 10.3 MHz analog input @ 0.5 dBFS, C
= 5 pF.
