●Description
This gamma correction voltage generation IC feature built-in DACs and provide a 1chip solution with setting control via serial
communications, a high-precision 10-bitDAC, and Buffer Amp (12ch).
●Features
1) 1chip design means fewer components
2) Built-in 10bit DAC
3) DAC output Buffer AMP (12ch)
4) Amp input select (CTL)
5) 3-line serial interface control
6) Thermal shut down
7) Power ON Reset Circuit
8) VQFN032V5050 Package
●Applications
These ICs can be used with TFT LCD Panels used by Large-Screen and High-Definition LCD TVs.
●Absolute maximum ratings (Ta=25℃)
