The MAX9679A provides multiple programmable reference voltages for gamma correction in TFT LCDs and a programmable reference voltage for VCOM adjustment. All gamma and VCOM 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 VCOM codes can be stored in the IC's volatile memory; BKSEL signal selects between the two sets.
