The ISL24833 is an 18-channel, 10-bit I2C programmable reference voltage generator for TFT-LCDs with dual bank outputs. It also provides an I2C programmable, 1-channel, 8-bit VCOM calibrator with VCOM 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 capable of storing all reference voltage data. The EEPROM is capable of >300 write cycles.
Combining gamma and VCOM 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 QFN thermally enhanced package. It is specified for operation over the -40°C to +85°C temperature range.
