MAX9679A
MAX9679A is 10-Bit Programmable Gamma and VCOM Reference Voltages manufactured by Maxim Integrated.
Description
The MAX9679A provides multiple programmable reference voltages for gamma correction in TFT LCDs and a programmable reference voltage for V adjustment. All gamma and V reference voltages have a 10-bit digital-to-analog converter (DAC) and high- current buffer, which reduces the recovery time of the output voltages when critical levels and patterns are displayed. A programmable internal reference sets the full-scale voltage of the DACs.
Two independent sets of gamma curves and V codes can be stored in the IC's volatile memory; BKSEL signal selects between the two sets.
