AD120 3-Level / 258 Outputs TFT LCD Gate Driver is a gate driver for TFT LCD panel. There are 258 outputs in the chip. Three-level output allows voltage correction for better switching noise rejection. It can be used for XGA / SXGA panels.
The AMIC AD120 is a gate driver designed specifically for TFT LCD panels. It features 258 outputs and utilizes a 3-level output structure to allow voltage correction, which improves switching noise rejection. The device supports both XGA and SXGA panel resolutions.
The chip includes a bi-directional data shift register controlled by the R/L signal, allowing sequential output of signals from OUT0 to OUT257 or vice versa. It provides three distinct output levels (VH, VL, VOFF) selectable via control pins like OGW, XON, and XOFF.
| Number of Outputs | 258 outputs |
|---|---|
| Output Voltage Range (Max) | 40V max. |
| Logic Input/Output Level | 2.7V~3.6V |
| Supply Voltage (VDD) | 2.7V to 3.6V |
The maximum voltage difference between VH and Vi is 40V.
