MAX9590
The MAX9590 provides 14 programmable
voltage references and 4 static
voltage references for gamma correction in TFT-LCD displays.
Two register banks are provided to store two sets of gamma reference values.
Gamma values are programmed into the banks through the I2C* interface and the outputs can switch between values in 0.
5µs.
The 14 programmable reference
voltages are divided evenly into seven upper and seven lower v...
