GENERAL DESCRIPTION
The ADV7127 (ADV®) is a high speed, digital-to-analog convertor on a single monolithic chip. It consists of a 10-bit,
video D/A converter with on-board voltage reference, complementary outputs, a standard TTL input interface and high
impedance analog output current sources.
The ADV7127 has a 10-bit wide input port. A single +5 V/
+3.3 V power supply and clock are all that are required to make
the part functional.
The ADV7127 is fabricated in a CMOS process. Its monolithic
CMOS construction ensures greater functionality with lower
power dissipation. The ADV7127 is available in a small outline
28-lead SOIC or 24-lead TSSOP package.
The ADV7127 TSSOP package also has a power-down mode.
Both ADV7127 packages have a power standby mode.
The ADV7127 TSSOP package has an on-board voltage reference circuit. The ADV7127 SOIC package requires an external
reference.
PRODUCT HIGHLIGHTS
1. 240 MSPS Throughput.
2. Guaranteed monotonic to 10 bits.
3. Compatible with a wide variety of high resolution color
graphics systems including RS-343A and RS-170A.
