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 ADV7172/ADV7173 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.

NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause permanent

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 conditions 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 48-lead LQFP package is used for this device. The junc-

tion-to-ambient (

θJA) thermal resistance in still air on a four

layer PCB is 54.6

°C/W. The junction-to-case thermal resistance

(

θJC) is 16.7°C.

To reduce power consumption when using this part the user is

advised to run the part on a 3.3 V supply, turn off any unused

DACs. However, if 5 V operation is required the user can enable

Low Power mode by setting MR16 to a Logic 1. Another alter-

native way to further reduce power is to use external buffers that

dramatically reduce the DAC currents, the current can be low-

ered to as low as 5 mA (see AN-551 and Appendix 8 for more

details) from a nominal value of 36 mA.

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)

× θ

JA ] 70

°C

where

IDAC = 10 mA + (sum of the average currents consumed by each

powered-on DAC).
