It operates from a single 9V to 20V supply and is housed in a 24-VFQFN exposed pad package (24-VQFN, 4x4 mm). The rail-to-rail output capability lets it swing close to the supply rails, which is necessary to set the VCOM voltage precisely across the panel's common electrode. With 12 independent buffer circuits, this IC can drive multiple VCOM lines in a large-format TFT-LCD, or it can be used to distribute the VCOM reference to several sections of the panel. Each channel's rail-to-rail output ensures the VCOM voltage stays within the desired range even as the load varies with the display content. The 9V to 20V supply range covers the typical VCOM bias voltages used in LCD panels, from small portable displays up to larger desktop or industrial monitors. ## Package and mounting The part is available on Tape & Reel or Cut Tape, which suits both prototyping and production reflow.","metaTitle":"BUF12840AIRGET TFT-LCD VCOM Driver, 12-Ch Rail-to-Rail","metaDescription":"Texas Instruments BUF12840AIRGET 12-channel rail-to-rail VCOM driver for TFT-LCD panels. 9V~20V supply, 24-VQFN package.
