GENERAL DESCRIPTION

The TDA8772 is a triple 8-bit video Digital-to-Analog

Converter (DAC). It converts the digital input signals into

analog voltage outputs at a maximum conversion rate of

35 MHz (TDA8772H/3) and 85 MHz (TDA8772H/8).

The DAC is based on resistor-string architecture with

integrated output buffers. The output voltage range is

determined by a built-in reference source.

The device is fabricated in a 5 V CMOS process that

ensures high functionality with low power dissipation.

APPLICATIONS

• General purpose high-speed digital-to-analog

conversion

• Digital TV

• Graphic display

• Desktop video processing.
