Description
The MAX5679 digitally programmable LCD gamma reference generator provides 18 buffered
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 I²C 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 -40°C to +85°C extended temperature
range.
