Gamma and VCOM Reference Voltages  
5/MAX967  
General Description  
Features  
The MAX9665/MAX9666/MAX9667 provide multiple  
programmable reference voltages for gamma correc-  
tion in TFT LCDs and a programmable reference volt-  
age for VCOM adjustment. All gamma and VCOM  
reference voltages have a 10-bit digital-to-analog con-  
verter (DAC) and buffer with high peak current. This  
reduces the recovery time of the output voltage when  
critical levels and patterns are displayed.  
o 6/8/10 Channels Gamma Correction, 10-Bit  
Resolution  
o VCOM Driver  
o Integrated Multiple-Time Programmable Memory  
o DAC Reference Input  
o Single-Wire and I2C Programming of VCOM  
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.  
Reference  
o 950mA Peak Transient Current on VCOM Channel  
The MAX9665/MAX9666/MAX9667 feature an I2C inter-  
face to control the programmable reference voltages  
and a single-wire interface to toggle the VCOM refer-  
ence voltage up or down.
