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.
