MAX9665, MAX9666, MAX9667
6/8/10-Channel, 10-Bit, Nonvolatile Programmable Gamma and VCOM Reference Voltages
Integrated Nonvolatile Programmable Gamma and VCOM Reference System for LCDs
|
Status
Active: In Production.
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.
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.
