The new AD8382 is a solution geared towards HTPS panels that reads 12-bit pixel data from a 12-bit bus at a sampling rate of up to 120Msps. Each of six sources is sequentially multiplexed into six separate high-speed DACs, which then drive 6-channels of high-output-voltage amplifiers. The high-speed output amplifiers settle quickly into capacitive loads. The flexible interface inherent in the DecDriver architecture allows for a modular design approach for high-quality projection systems with resolutions up to SXGA and beyond.

The AD8382 eliminates external amplifiers and calibration cycles through integrated amplifiers that deliver full 9 to 18V dynamic range output signals that are laser-trimmed, accurate, and fast settling. With a flexible digital input interface, several AD8382s can be used in parallel for higher resolution displays. The AD8382 eases front or rear projection system design through multiplexing latches that can be loaded left to right, or vice-versa. It includes logic-controlled inversion, as well as voltage-controlled mid-scale, brightness and contrast.

The AD8382 is available in a 48-lead 7 x 7 x 1.4mm LFCSP package that dramatically reduces the size of the LCD projector drive electronics board. The device operates over the temperature range of 0 to +85°C. It is priced at $8.00 per unit in 1,000-piece quantities.
