GENERAL DESCRIPTION
The ADV7125 (ADV®) is a triple high speed, digital-to-analog
converter on a single monolithic chip. It consists of three high
speed, 8-bit video DACs with complementary outputs, a
standard TTL input interface, and a high impedance, analog
output current source.
The ADV7125 is fabricated in a 5 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation. The ADV7125 is available in
48-lead LQFP and 48-lead LFCSP packages.
PRODUCT HIGHLIGHTS
The ADV7125 has three separate 8-bit-wide input ports. A
single +5 V/+3.3 V power supply and clock are all that are
required to make the part functional. The ADV7125 has
1. 330 MSPS (3.3 V only) throughput.
2. Guaranteed monotonic to eight bits.
3. Compatible with a wide variety of high resolution color
graphics systems, including RS-343A and RS-170.
