GENERAL DESCRIPTION
The ADV®7330 is a high speed, digital-to-analog encoder on a
single monolithic chip. It includes three high speed video D/A
converters with TTL compatible inputs.
The ADV7330 has separate 8-bit or 16-bit input ports that
accept data in high definition or standard definition video
format. For all standards, external horizontal, vertical, and
blanking signals or EAV/SAV timing codes control the inser-
tion of appropriate synchronization signals into the digital
data stream and therefore the output signal.
Purchase of licensed I2C components of Analog Devices or one of its
sublicensed Associated Companies conveys a license for the purchaser under
the Philips I2C Patent Rights to use these components in an I2C system,
provided that the system conforms to the I2C Standard Specification as
defined by Philips.

NOTES
1 Stresses 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 section
of this specification is not implied. Exposure to absolute maximum ratings for
extended periods may affect device reliability.
2 Analog output short circuit to any power supply or common can be of an indefinite
duration.

THERMAL CHARACTERISTICS
JC = 11°C/W
JA = 47°C/W
The ADV7330 is a Pb-free, environmentally friendly product. It is
manufactured using the most up-to-date materials and processes.
The coating on the leads of each device is 100% pure Sn electro-
plate. The device is suitable for Pb-free applications, and is able
to withstand surface-mount soldering at up to 255°C (± 5°C).
In addition, it is backward compatible with conventional SnPb
soldering processes. This means that the electroplated Sn coating
can be soldered with Sn/Pb solder pastes at conventional reflow
temperatures of 220°C to 235°C.

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
ADV7330 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.
