REG

Output voltage stable under transient load conditions

APPLICATIONS

TFT LCD monitor panels

TFT LCD TV panels

GENERAL DESCRIPTION

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_DDand 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.
