The ADD8709 is an 18-channel gamma reference for use in high-resolution TFT LCD monitor and TV panels. The output buffers feature low offset voltage and high current drive under transient load conditions to provide a more accurate and stable gamma cur ve. Two channels swing to VDD and two channels swing to GND, increasing the overall range of the cur ve. An on-board voltage regulator is available for external applications. Here again, external component costs are reduced and the quality of the gray scale is increased.
