General Description

o o o o

Key Features

  • 14 Programmable Reference Voltages 4 Static Reference Voltages Independent DACs with 8-Bit Resolution 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 even.

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 voltages for the upper and lower gamma curves of LCD column drivers.
