12-Channel Gamma Buffers With VCOM Buffer

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.
The ADD8702 provides a complete programmed set of gamma Voltage References for the LCD source drivers. These references settle quickly to load change. The VCOM output is stable with high capacitive loads and CAN source or sink 250 mA peak current. The VCOM output level CAN be adjusted using an external trim-potentiometer or Discrete resistors. The output pins are compatible with the ADD8701. This allows for single board design and fast turns for prototyping using the initial ADD8701 board design. The ADD8702 is specified over the temperature range of 40C to +85C and comes in the 32-lead lead frame chip scale package (LFCSP) for compact board space.
