BUF12840AIRGET TI Programmable Gamma Buffer | 24-VQFN (4x4) | 12-Ch, 18V, 10mA

Product Overview

The BUF12840AIRGET from Texas Instruments is a 12-channel programmable gamma buffer designed for TFT-LCD panel applications. It integrates 12 buffer amplifiers with 8-bit programmable gamma correction, providing precise voltage levels for LCD column drivers. Housed in a compact 24-VQFN (4x4 mm) package, it operates over a wide supply range of 4.5V to 18V and delivers up to 10mA output current per channel. This device simplifies gamma correction design, reduces component count, and improves display uniformity.
