MAX5679 Overview
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...
