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, s
