TDA8772
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.
