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 specification 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

indefinite duration.

PACKAGE THERMAL PERFORMANCE

The 64-lead package is used for this device. The junction-to-

ambient (θJA) thermal resistance in still air on a four-layer PCB

is 38°C/W.

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 )/RSET

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 ADV7190/ADV7191 features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precau-

tions are recommended to avoid performance degradation or loss of functionality.
