Rev 2.00
August 2, 2012 15-Channel I2C Programmable TFT-LCD Reference Voltage Generator with Integrated
EEPROM, and Ultra-Low Power Operation
The ISL24858 is a programmable reference voltage generator
for TFT-LCDs featuring ultra-low power operation. The
ISL24858 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.
Combining gamma and VCOM reference voltage generators
with low power operation and EEPROM, the ISL24858 provides
a complete reference voltage solution ideal for tablet, monitor,
and mobile TFT-LCD applications.
The ISL24858 is available in a super thin 28 Ld 4x5mm
X2QFN thermally enhanced package. It is specified for
operation over the -40В°C to +105В°C ambient temperature
range. Features 15-Channel Reference Voltage Outputs, I2C Programmable:
-14-Channel Gamma References, 10-bit Resolution with
Buffered Outputs …
