MAX9673 Datasheet Programmable Gamma Reference Systems

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4718; Rev 4; 2/11 EVAALVUAAILTAIOBNLEKIT 10-Bit, Programmable Gamma Reference Systems with MTP for TFT LCDs MAX9672/MAX9673/MAX9674.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features
