ABSOLUTE MAXIMUM RATINGS
STRESS RATINGS
Stresses 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.

ESD 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 this product 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.
Analog output short circuit to any power supply or common can be of an
indefinite duration.

PACKAGE THERMAL PERFORMANCE
The 44-lead MQFP package used for this device has a junction-
to-ambient thermal resistance (θ
of 53.2°C/W. The junction-to-case thermal resistance (θ
18.8°C/W. Care must be taken when operating the part in
certain conditions to prevent overheating. Table 8 lists the
conditions to use when using the part.

DAC on, double 75 R refers to a condition where the DACs are terminated
into a double 75 R load and low power mode is disabled.
DAC on, low power refers to a condition where the DACs are terminated in
a double 75 R load and low power mode is enabled.
DAC on, buffered refers to a condition where the DAC current is reduced to
5 mA and external buffers are used to drive the video loads.
