NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specication is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
2Analog Output Short Circuit to any Power Supply or Common can be of an
indenite duration.
PACKAGE THERMAL PERFORMANCE
The 80-lead package is used for this device. The junction-to-
ambient (
θ
JA) thermal resistance in still air on a four-layer PCB
is 24.7
°C.
To reduce power consumption when using this part the user
can run the part on a 3.3 V supply, turn off any unused DACs.
The user must at all times stay below the maximum junction
temperature of 110
°C. The following equation shows how to
calculate this junction temperature:
Junction Temperature = (VAA
× (IDAC + ICCT)) × θJA + 70°C (TAMB)
IDAC = 10 mA + (sum of the average currents consumed by
each powered-on DAC)
Average current consumed by each powered-on DAC =
(VREF
× K )/R
SET
VREF = 1.235 V
K = 4.2146

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADV7194 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
