The ISL76534 is a programmable gamma buffer for TFT-LCDs featuring ultra-low power operation. The ISL76534 contains an I2C programmable, 10-bit, 14-channel gamma reference voltage generator with buffered outputs, a 10-bit programmable VCOM calibrator, a high output current VCOM amplifier, and internal EEPROM to store all reference voltage data. The EEPROM features an endurance of 10, 000 write cycles and a data retention of 20 years at 105°C. Combining gamma and VCOM reference voltage generators with low power operation and EEPROM, the ISL76534 provides a complete reference voltage solution ideal for TFT-LCD displays. The ISL76534 is available in a super thin (height = 0. 4mm maximum) 28 Ld 4mmx5mm X2QFN thermally enhanced package. The device is specified for operation across the ambient temperature range of -40°C to +105°C.
