MAX9668 Datasheet - ETC

MAX9668 LCD Gamma Buffer

The MAX9668 outputs eight 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 stable voltage. The VCOM reference voltage has its own 10-bit DAC and an amplifie.

MAX9668 Features

* integrated multiple-time programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The MAX9668 supports up to 100 write operations to the on-chip nonvolatile memory. The gamma outputs can drive 200mA peak transient current and settle within 1µs.
