GENERAL DESCRIPTION
The ADD8709 is an 18-channel integrated gamma reference for use in 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 and the lower nine channels swing to GND.
An on-board voltage regulator provides a fixed input for the gamma buffers, isolating the gamma curve from supply ripple.
The ADD8709 is specified over the temperature range of
- 40°C to +105°C and es in a 48-lead, Pb-free, low-profile quad flat package.
