The ISL24867 contains an I2C programmable, 10-bit, 14-channel gamma reference voltage generator with buffered dual bank outputs, an 8-bit programmable DVR VCOM calibrator, high output current VCOM amplifier, and a GND outputs function with logic (EN) control. The integrated EEPROM, for storing all reference voltage data, features an endurance of 10,000 write cycles and is read/write capable over the digital supply voltage range. • 15-Channel Reference Voltage Outputs, I2C Programmable The dual bank outputs are capable of fast switching between different sets of voltage reference data. Bank switching is ideal to quickly change between gamma curves for 2D/3D TFT-LCD applications. The device’s outputs are double buffered, which allows for updating data in one bank while data is simultaneously output from the other bank. - 14-Channel Gamma References, 10-bit Resolution with Buffered Dual Bank Outputs - 1-Channel VCOM Calibrator (“DVR”), 8-bit Current-Sink DAC • High Output Current VCOM Amplifier • Dual Bank Gamma Output, with Fast Output Bank Switching • GND Outputs Function, with Logic Control • Ultra-low Power Operation, Ideal for Tablet and Mobile TFT-LCD Applications: Quiescent Power 13mW @ 8V AVDD • EEPROM Endurance: 10,000 Write Cycles - Read/Write Capable Over 2.25V to 3.6V DVDD Range • 6.3V to 19V Analog Supply Operating Range • 2.25V to 3.6V Digital Supply Operating Range Combining gamma and VCOM reference voltage generators, with low power operation, and EEPROM, the ISL24867 provides a complete reference voltage solution ideal for tablet, monitor, and mobile TFT-LCD applications. • 28 Ld 4x5mm Super Thin X2QFN Package The ISL24867 is available in a Super Thin 28 Ld 4x5mm X2QFN thermally enhanced package.
