BUF20800ATDCPRQ1, LCD Gamma Buffers AUTO CAT 18CH GAMMA VLTG GEN
Semiconductors\Integrated Circuits - ICs\Amplifier ICs\LCD Gamma BuffersBUF20800 18-Channel Gamma Voltage Generator
Texas Instruments BUF20800 18-Channel Gamma Voltage Generator is a programmable voltage reference generator designed for gamma correction in TFT-LCD panels. It provides 18 programmable outputs for gamma correction and two channels for V COM adjustment, each with 10-bit resolution. This programmability replaces the traditional, time consuming process of changing resistor values to optimize the various gamma voltages and allows designers to determine the correct gamma voltages for a panel very quickly. Required changes can also be easily implemented without hardware changes. The BUF20800 uses TI"s latest, small-geometry analog CMOS process, which makes it a very competitive choice for full production, not just evaluation. Programming of each output occurs through an industry standard, two-wire serial interface. Unlike existing programmable buffers, the BUF20800 offers a high-speed mode that allows clock speeds up to 3.4MHz.
