General Description
The MAX9672/MAX9673/MAX9674 output 12/14/16 voltage references for gamma correction in TFT LCDs and one voltage reference for VCOM. Each gamma reference voltage has its own 10-bit DAC and buffer to ensure a stable voltage. The VCOM reference voltage has its own 10-bit DAC and an amplifier to ensure a stable voltage when critical levels and patterns are displayed. The MAX9672/MAX9673/MAX9674 feature integrated multiple-time programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The MAX9672/ MAX9673/MAX9674 support up to 300 write operations to the on-chip nonvolatile memory.
