GENERAL DESCRIPTION

The ADD8502 is an integrated, high accuracy, programmable grayscale generator. Two sets of five output reference voltages are mask programmed to 0.2 resolution. The outputs switch between the two sets of five levels. The reference levels are selected from a 512 tap resistor network using a via mask.
