GENERAL DESCRIPTION
The TDA8775 consists of three 10-bit video
Digital-to-Analog Converters (DACs). They convert the
digital input signals into current outputs at a maximum
conversion rate of 50 MHz.
The DACs are based on current source architecture with
selectable current reference.
The devices are fabricated in a 5 V CMOS process that
ensures high functionality with low power dissipation.
