The ADV7123-EP is a triple, high speed digital-to-analog
converter (DAC) on a single monolithic chip. It consists of three
high speed, 10-bit video DACs with complementary outputs,
a standard TTL input interface, and a high impedance, analog
output current source.
The ADV7123-EP has three separate 10-bit-wide input ports.
A single 3.3 V power supply and clock are the only components
required to make the part functional. The ADV7123-EP has
additional video control signals: composite SYNC and BLANK.
The ADV7123-EP also has a power save mode.
The ADV7123-EP is fabricated in a 5 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation. The ADV7123-EP is available
in a 48-lead LFCSP package.
Full details about this enhanced product are available in the
ADV7123 data sheet, which should be consulted in conjunction
with this data sheet.
1. Guaranteed monotonic to 10 bits.
2. Compatible with a wide variety of high resolution color
graphics systems, including RS-343A and RS-170.
