description

The ISL24858 is a programmable reference voltage generator for TFT-LCD with ultra-low power operation. The ISL24858 contains an I2C programmable 14-channel 10-bit, gamma-referenced voltage buffer output, a 10-bit programmable VCOM calibrator, a high output current VCOM amplifier, and an internal EEPROM to store all reference voltage data generators. EEPROM features a 10,000-write cycle endurance. Combining low power operation and EEPROM, the ISL24858 provides an ideal solution for TFT-LCD applications with a complete voltage reference for tablets, displays and mobile phones, and the ISL24858 is a gamma and VCOM reference generator. Ultra-thin 28 LD 4x5mm X2QFN thermally enhanced package. It specifies operation over an ambient temperature range of -40°C to +85°C.LM3S1968-IQC50-A2
