NCS12802
12-Channel I2C Programmable Gamma Voltage Reference Generator with Integrated Auto-read
The NCS12802 is a 12− channel programmable voltage reference generator providing the gamma correction references to the TFT−LCD panel through the source driver circuit.
The twelve output voltage references are programmed through an I2C interface which can operate at standard and high speed. The output buffers can be finely tuned due to the 10 bit DAC precision (1024 steps). In addition, the NCS12802 features an auto−read function which allows uploading binary data from an external EEPROM. To support this capability, the device can act as both slave and master I2C.
In order to accelerate the dynamic correction process, the NCS12802 has two separate register banks.
