UPD16448A

DATA SHEET MOS INTEGRATED CIRCUIT µPD16448A SOURCE DRIVER FOR 240-OUTPUT TFT-LCD (NAVIGATION, AUTOMOBILE LCD-TV) µPD16448A is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a variety 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 LCDTVs. FEATURES Can be driven on 5 V (Dynamic range: 4.3 V, VDD2 = 5.0 V) 240-output fmax. = 18 MHz (VDD1 = 3.0 V) Simultaneous/successive sampling selectable according to pixel array Simultaneous sampling: vertical stripe Successive sampling: Two sample and hold circuits Low output deviation between pins (± 20 mV MAX.) Stripe, delta, and mosaic pixel arrays supported by internal multiplexer circuit Left and right shift selected by R/L pin Single-side mounting possible delta array, mosaic array ORDERING INFORMATION Part Number µPD16448AN-××× Package TCP (TAB package) Remark The dimensions of TCP are custom-made.
