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.
