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, comple mentary 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.
