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. Applications * TFT LCDs * 6/8/10 Channels Gamma Correction, 10-Bit Resolution * VCOM Driver * Integrated Multiple-Time Programmable Memory * DAC Reference Input * Single-Wire and I²C Programming of VCOM Reference * 950mA Peak Transient Current on VCOM Channel
