MAX9669 - 10-Bit Programmable Gamma Reference System

MAX9669 Description

19-4326; Rev 4; 8/11 MAX9669 10-Bit Programmable Gamma Reference System with MTP for TFT LCDs General .
The MAX9669 outputs 16 voltage references for gamma correction in TFT LCDs and one voltage reference for VCOM.

MAX9669 Features

* integrated multiple-time programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The MAX9669 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.
