Description
The TMC3503 is a high-speed triple 8-bit D/A converter
especially suited for video and graphics applications.
It offers 8-bit resolution, TTL-compatible inputs, low power
consumption, a power-down sleep mode, 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 any D/A converter
output. WHITE and SLEEP control inputs are available on
PLCC parts. It is ideal for generating analog RGB from
digital RGB and driving computer display and video moni-
tors. Three speed grades are available: 30, 50, and 80 Msps.
The TMC3503 triple D/A converter is available in a 44-lead
plastic J-leaded PLCC. It is also available in a 48-lead plastic
LQFP package. It is fabricated on a sub-micron CMOS
process with performance guaranteed from 0°C to 70°C.
