ADD8708 - 18-Channel Gamma Buffer

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.

Features

  • 18 precision gamma reference outputs Mask-programmable gamma resistors: 0.2% resolution and 0.1% accuracy Mask-programmable voltage regulator: 0.4% accuracy Upper 9 buffers swing to VDD Lower 9 buffers swing to GND Single-supply operation: 7.5 V to 16.5 V Gamma current drive: 15 mA per channel Peak output current: 150 mA Output voltage stable under load conditions Pin-to-pin compatible with ADD8709 48-lead, Pb-free LQFP and LFCSP.
