Product data sheet

1. General description

The TDA8777 consists of three separate 10-bit video Digital-to-Analog Converters (DACs)

with complementary outputs. They convert the digital input signals into analog current

outputs at a maximum conversion rate of 330 MHz.

The DACs are based on current source architecture.

A sync pulse can be added to the green signal (sync-on-green) to allow devices driven by

the video DAC to be synchronized.

The TDA8777 has a Power-down mode to reduce power consumption during inactive

periods.

The TDA8777 is fabricated in a CMOS process that ensures high functionality with low

power dissipation.
