DATA SHEET MOS INTEGRATED CIRCUIT µPD16449 SOURCE DRIVER FOR 240-OUTPUT TFT-LCD (NAVIGATION, AUTOMOBILE LCD-TV) DESCRIPTION µPD16449 is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a www.DataSheet4U.comvariety of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample analog voltages. Because the two sample and hold circuits alternately execute sampling and holding, a high definition can be obtained. In addition, simultaneous sampling and successive sampling are automatically selected according to the pixel array of the LCD panel. It is ideal for a wide range of applications, including navigation systems and automobile LCD-TVs. FEATURES • Can be driven on 5 V (Dynamic range: 4.
