Description
The TMC3533 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 +3.3V±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 monitors. Three speed grades are available: 30, 50, and
80 Msps.
The TMC3533 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 pro-
cess with performance guaranteed from 0°C to 70°C.
