BUF12800 用于 LCD 伽马校正的参考电压生成器
The BUF12800 is a programmable voltage reference generator designed for dynamic gamma correction in TFT-LCD panels. It provides 12 programmable outputs, each with 10-bit resolution.
TI’s new, small geometry, state-of-the-art, analog CMOS process allows the use of one digital-to-analog converter (DAC) per channel while still maintaining a very small chip size. This topology has the advantage of significantly increased programming speed over existing programmable buffers.
Programming of each output occurs through an industrystandard, two-wire serial interface. Unlike existing programmable buffers, the BUF12800 offers a highspeed, two-wire interface mode that allows clock speeds up to 3.4MHz. The BUF12800 features a double-buffered DAC register structure that significantly simplifies implementation of dynamic gamma control.
