The LP6299 providers a 14-channel programmable gamma buffer and a programmable VCOM buffer for applications in TFT-LCD Panel. Each of the 14-channel gamma buffers is generated using a 10-bit resolution digital-to-analog converter together with a buffer through IIC control. The 14-channel gamma buffer support dynamic switching between two gamma curves by selecting BANK select pin.The LP6299 also features a programmable operational amplifier that drives the LCD VCOM. This unity-gain buffer is capable of rail-to-rail input and output, fast slew rate, and ±150mA output short-circuit current. The VCOM buffer voltage is IIC programmed using 7-bit resolution. The LP6299 includes EEPROM to store two gamma codes and VCOM codes, and control it through IIC interface at the real time. The LP6299 is available in a space saving QFN32 (0.5mm pitch) package.
