LP6298QVF 微源14CH可编程伽玛和VCOM缓冲器
General Description
The LP6298 providers a 14-channel programmable gamma buffer and 1-channel 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 LP6298 also features a programmable operational amplifier that drives the LCD VCOM. This unity-gain buffer is capable of rail-to-rail output, fast slew rate, and ±140mA output short-circuits current.
The VCOM buffer voltage is IIC programmed using 7-bit resolution.
The LP6298 includes EEPROM to store gamma codes and VCOM codes, and control it through IIC interface at the real time.
The LP6298 is available in a space saving QFN24 (0.5mm pitch) package.
