MAX9667 - Nonvolatile Programmable Gamma and VCOM Reference Voltages

Download the MAX9667 datasheet PDF. This datasheet also covers the MAX9665 variant, as both devices belong to the same nonvolatile programmable gamma and vcom reference voltages family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

19-5000; Rev 4; 7/10 MAX9665/MAX9666/MAX9667 6/8/10-Channel, 10-Bit, Nonvolatile Programmable Gamma and VCOM Reference Voltages General Description 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 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 300 write operations.
