GENERAL DESCRIPTION
The TDA8771A 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.
The DACs are 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.
