It also provides an 2c programmable, 1-channel, 8-bit Vcoy calibrator with Vcoy amplifier and internal EEPROM. The two output banks are capable of switching quickly (<1ys) enabling rapid switching between two gamma cures (or operational modes) in TFT-LCD applications. The ISL24833 also integrates two banks of EEPROM capable of storing all reference voltage data. The EEPROM is capable of >300 write cycles. Combining gamma and Vcow reference voltage generators with low power operation and EEPROM, the ISL24833 provides a complete reference voltage solution ideal for large area TFT-LCD display applications. ISL24833 is available in a 32 Ld 5mmx6mm QEN thermally enhanced package. It is specified for operation over the -40C to +85C temperature range.
