GENERAL DESCRIPTION

The ADV7127 (ADV

vertor 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 refer-

ence 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.
