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.
TIs 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. This further reduces programming time, especially when many channels have to be updated simultaneously.
Reference pins set the high and low voltages of the output range. They are internally buffered, which simplifies design. They may be connected to external resistors to divide the output range for finer resolution of outputs.
The BUF12800 is available in a TSSOP-24 PowerPAD package. It is specified from 40°C to +85°C.
