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 LCD-
TVs.
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: delta array, mosaic array
• 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
