LM8207 TFT 18 Gamma Buffer VCOM Driver Voltage Reference

The LM8207 is a combination of 18-channel gamma buffers, a VCOM driver and a temperature compensated internal voltage reference. It is designed for buffering voltage levels and driving high capacitive loads in large TFT panels. The gamma buffers are individually optimized to the input/output require.
