Description The MAX5679 digitally programmable LCD gamma reference generator provides 18 buffered Request Full Data Sheet channels for biasing LCD column drivers. The device provides 14 outputs of 8-bit programmable gamma reference voltage derived from four externally applied reference voltages, and four buffered outputs of the same externally applied reference voltages. An IC serial interface programs the 14 upper and lower range gamma buffer outputs independently. The MAX5679 features a digitally programmable voltage reference (DVR) with 7-bit adjustable current sink to set the LCD common backplane (VCOM) voltage. The MAX5679 includes a power-on reset (POR) function that configures all 14 programmable gamma outputs to predetermined levels upon initial power-up. The MAX5679 is available in a 5mm x 5mm, 32-pin TQFN package and is specified over the -40C to +85C extended temperature range.
