GENERAL DESCRIPTION
The ADD8702 is a low cost, mask programmable, 12-channel gamma reference generator, plus an adjustable VCOM driver. This part is designed to provide gamma correction for high resolution TFT LCD panels. The 12 gamma reference levels and VCOM are mask programmable to 0.3% resolution using the on-chip 500 chain resistor string. This reduces component and board costs.
