Product introduction

This is a programmable reference voltage source BUF16820 gamma correction generator design TFT-LCD panel.It provides 14 programmable outputs and two Wycombe channels, each with a digital resolution.It provides on-chip, one-time programming (net) memory. It allows the user to store gamma voltage on-chip.This eliminates the need for an external EEPROM.

This programmable alternative to the traditional, time-consuming process of changing resistors optimizes various gamma voltages and allows designers to determine the correct gamma voltage to act on a panel very quickly.The required voltage change is also easily achieved without changing the hardware.

Using titanium's latest BUF16820, small-geometry simulates the CMOS process, which makes it a very competitive option for more than just evaluating mass production.
