Product Summary

The MAX9674ETI+ is a kind of 10-Bit, Programmable Gamma Reference System with MTP for TFT LCDs. Each gamma reference voltage has its own 10-bit DAC and buffer toensure a stable voltage. The VCOM reference voltage its own 10-bit DAC and an amplifier to ensure a stable voltage when critical levels and patterns are displayed.The MAX9674ETI+ features integrated multiple-time programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The MAX9674ETI+ supports up to 300 write operations to the on-chip nonvolatile memory.
