| MAX9679B 12-Channel, 10-Bit Programmable Gamma and VCOM Reference Voltages The MAX9679B 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 highcurrent 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. The IC has multiple-time programmable MTP memory to store gamma and VCOM codes on the chip, eliminating the need for external EEPROM.
