描述 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.
