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.
