GENERAL DESCRIPTION
The ADD8504/ADD8505/ADD8506 evaluation board
simplifies evaluation of the
under various conditions. This evaluation kit includes a gamma
voltage calculator, labeled ADD8504-05-06 Gamma Voltage
Calculator.xls, on the ADD8504/ADD8505/ADD8506
evaluation board kit CD to assist in determining required
external components to implement the desired gamma voltages.
This documentation is for the ADD8504/ADD8505/ADD8506
evaluation board only; for specific information regarding the
ADD8504/ADD8505/ADD8506
LCD gamma buffers, please refer to the datasheet.
