NOTES

1All measurements are made in 4

¥ Oversampling Mode unless otherwise speciﬁed and are guaranteed by characterization. In 2¥ Oversampling Mode, the power re-

quirement for the ADV7190/ADV7191 are typically 3.0 V.

2Temperature range T

MIN to TMAX: 0

∞C to 70∞C.

3Measurement made in 2

¥ oversampling mode.

4I

DAC is the total current required to supply all DACs including the V REF circuitry.

5All six DACs ON.

6I

CCT, or the circuit current, is the continuous current required to drive the digital core without I PLL.

Speciﬁcations subject to change without notice.

(VAA = 3.3 V, VREF = 1.235 V, RSET1,2 = 1200

, unless otherwise noted. All speciﬁcations TMIN to TMAX

2,

unless otherwise noted.)
