MAX9679A Datasheet (Maxim Integrated) - 10-Bit Programmable Gamma and VCOM Reference Voltages

MAX9679A, 10-Bit Programmable Gamma and VCOM Reference Voltages

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
