GENERAL DESCRIPTION  
The ADD8708 is an 18-channel integrated gamma reference for  
use in high resolution LCD TV and monitors panels. The out-  
put 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.

Integrating the gamma setup resistors drastically reduces the  
external component count while increasing the gamma curve  
accuracy. To accommodate multiple column drivers and panel  
architectures, the ADD8708 is mask programmable to a 0.2%  
resolution using the on-chip 500 resistor string. An on-board  
voltage regulator provides a fixed input for the resistor string,  
isolating the gamma curve from the supply ripple.

The ADD8708 is specified over the temperature range of  
–40°C to +105°C and comes in both a 48-lead, Pb-free,  
lead-frame chip-scale package and a Pb-free, low-profile,  
quad flat package.
