UPD16449, SOURCE DRIVER

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 hol
