CXA2111R
LCD Signal Processor (Gamma Correction)
Description
The CXA2111R is a signal processor IC developed
for LCD panels. Gamma correction, gain and bias,
etc., can be adjusted using the I²C bus and external
adjustment pins. The output of this IC is ideal as the
input of the CXA2112R (LCD sample-and-hold
driver IC), and the sample-and-hold position, etc.,
can also be adjusted using the I²C bus.
52 pin LQFP (Plastic)
