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 TMIN to TMAX: 0∞C to 70∞C.
3Measurement made in 2¥ oversampling mode.
4IDAC is the total current required to supply all DACs including the VREF circuitry.
5All six DACs ON.
6ICCT, or the circuit current, is the continuous current required to drive the digital core without I PLL.
Specifications subject to change without notice.
