UPD16449 Overview
Description
µPD16449 is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample analog voltages.
Key Features
- Can be driven on 5 V (Dynamic range: 4.3 V, VDD2 = 5.0 V)
- fCLK = 15 MHz MAX. (VDD1 = 3.0 V)
- 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
- TCP/COG mounting possible 5 Remark /xxx indicates active low signal
