GENERAL DESCRIPTION

The ADD8708 is an 18-channel integrated gamma reference for use in high resolution LCD TV and monitors panels. The output buffers feature high current drive and low offset voltage to provide an accurate and stable gamma curve. The top nine channels swing to VDD; the lower nine channels swing to GND.
