NOTES
1No 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.
2Gain 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 – AIN) = ± 0.5 V in 1 V range (full scale), (AIN – AIN) = ± 1 V in 2 V range (full scale).
4AC Power Dissipation measured with rated encode and a 10.3 MHz analog input @ 0.5 dBFS, C LOAD = 5 pF.
5DC Power Dissipation measured with rated encode and a dc analog input (Outputs Static, IV DD = 0)
6In power-down state IVDD = ± 10 µA typical (all grades).
Specifications subject to change without notice.
