MAX9665, MAX9666, MAX9667 6/8/10通道、10位、非易失可编程gamma和VCOM电压基准

概述

The MAX9665/MAX9666/MAX9667 provide multiple programmable reference voltages for gamma correction in TFT LCDs and a programmable reference voltage for VCOM adjustment. All gamma and VCOM reference voltages, have a 10-bit digital-to-analog converter (DAC), and buffer with high peak current. This reduces the recovery time of the output voltages voltage when critical levels and patterns are displayed.

These devices include multiple-time programmable (MTP) memory to store gamma and VCOM codes on the chip, eliminating the need for external EEPROM. The MTP memory supports up to 100 write operations.

The MAX9665/MAX9666/MAX9667 feature an I²C interface to control the programmable reference voltages and a single-wire interface to toggle the VCOM reference voltage up or down.
