Description

The TMC3003 is a high-speed triple 10-bit D/A converter

especially suited for video and graphics applications.

It offers 10-bit resolution, TTL-compatible inputs, low

power consumption, and requires only a single +5 Volt

power supply. It has single-ended current outputs, SYNC

and BLANK control inputs, and a separate current source for

adding sync pulses to the Green D/A converter output. It is

ideal for generating analog RGB from digital RGB and

driving computer display and video monitors. Three speed

grades are available: 30, 50, and 80 Msps.

The TMC3003 triple D/A converter is available in a 44-lead

plastic J-leaded PLCC and 48-Lead quad ﬂatpack (LQFP).

It is fabricated on a sub-micron CMOS process with perfor-

mance guaranteed from 0°C to 70°C.
