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 atpack (LQFP).
It is fabricated on a sub-micron CMOS process with perfor-
mance guaranteed from 0
°C to 70°C.
