LM8207 Datasheet (National Semiconductor) - TFT 18 Gamma Buffer VCOM Driver Voltage Reference

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
