Product Summary

The MAX9669ETI+ is a kind of 10-bit programmable gamma reference system with MTP for TFT LCDs. The MAX9669ETI+ outputs 16 voltage references for gamma correction in TFT LCDs and one voltage reference for VCOM. Each gamma reference voltage has its own 10- bit digital-to-analog converter (DAC) and buffer to ensure a table 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 MAX9669ETI+ features integrated multiple-time programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The MAX9669ETI+supports up to 100 write operations to the on-chip nonvolatile memory.
