July 27, 2011 18-Channel Programmable I2C TFT-LCD Reference Voltage Generator with Integrated
VCOM Calibrator and 2 Banks of EEPROM
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. Features The two output banks are capable of switching quickly (<1Вµs)
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. One VCOM Op Amp Two Banks of EEPROM Storage (Rewritable >300 times) 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. I2C Serial Interface ISL24833 is available in a 32 Ld 5mmx6mm QFN thermally
enhanced package. It is specified for operation over the -40В°C
to +85В°C temperature range. 18-Channel I2C Programmable 10-bit DACs Integrated I2C Programmable 8-bit VCOM Calibrator Fast Output Bank Switching: <1Вµs Typical Analog Supply: 12V to 18V @ 15mA (Unloaded) Digital Supply: 2.5V to 3.3V @ 1.3mA (Unloaded) Pb-free (RoHS compliant) Applications TFT-LCD Column Driver Reference Generator TFT-LCD VCOM Calibrator and Driver General-Purpose Reference Voltage Generators GAMMA VOLTAGES
