Output Voltage Stable under Transient Load Conditions

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 curve. Two channels swing to V_DD and two channels swing to GND, increasing the overall range of the curve. 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.

The ADD8709 is specified over the temperature range of –40°C to +100°C and comes in a robust, low profile quad flat package.
