NCS12802
12-Channel I2C
Programmable Gamma
Voltage Reference
Generator with Integrated
Auto-read
The NCS12802 is a 12channel programmable voltage reference
generator providing the gamma correction references to the
TFTLCD 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 autoread 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. It can simultaneously
store two different curves.
The NCS12802 is proposed in a QFN24 package and an operating
temperature range from 40°C to +95°C.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification
limit values are applied individually under normal operating conditions and not valid simultaneously.
7. Observe maximum power dissipation. Exposed thermal die is soldered to the PCB using thermal vias.
