Product Introduction

This is a programmable reference voltage source BUF12800 generator is designed as a dynamic gamma-corrected TFT-LCD panel.It offers 12 programmable outputs, each with a digital resolution.

Transparent International's new, small-geometric, leading-edge, analog CMOS process allows the use of a digital-to-analog converter (DAC) per channel while still maintaining a very small chip size.The advantage of this topology is that it significantly increases programming speed compared to existing programmable buffers.

Each output is programmed via an industrystandard, two-wire serial interface.Unlike existing programmable BUF12800 buffers, it offers a high-speed, two-wire interface mode that allows for speeds of 3.4MHz clocks.BUF12800 Double-Buffered features a structure that greatly simplifies DAC registration and implements dynamic gamma control.
