Low Power 15-Channel I2 C Programmable TFT-LCD Reference Voltage Generator with Integrated EEPROM

Product Status: 量産中

OVERVIEW

The ISL24858 is a programmable reference voltage generator for TFT-LCDs featuring ultra-low power operation. The ISL24858 contains an I2 C 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 -40°C to +105°C ambient temperature range.
