Renesas Electronics Corporation 18-Channel Programmable I²C TFT-LCD Reference Voltage Generator ISL24833IRZ

The ISL24833 is an 18-channel, 10-bit Isup2/supC programmable reference voltage generator for TFT-LCDs with dual bank outputs. It also provides an Isup2/supC programmable, 1-channel, 8-bit VsubCOM/sub calibrator with VsubCOM/sub amplifier and internal EEPROM. The two output banks are capable of switching quickly (1µs) enabling rapid switching between two gamma curves (or operational modes) in TFT-LCD applications. The ISL24833 also integrates two banks of EEPROM that can store all reference voltage data. The EEPROM is capable of 300 write cycles. Combining gamma and VsubCOM/sub 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. The ISL24833 is available in a 32 Ld 5mmx6mm QFN thermally enhanced package. It is specified for operation across the -40°C to +85°C temperature range.
