The ISL76534 is a programmable gamma buffer for TFT-LCDs

featuring ultra-low power operation. The ISL76534 contains an

I

2C 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 and a data retention of 20 years at 105°C.

Combining gamma and VCOM reference voltage generators

with low power operation and EEPROM, the ISL76534 provides

a complete reference voltage solution ideal for TFT-LCD

displays.

The ISL76534 is available in a super thin (height = 0.4mm

maximum) 28 Ld 4mmx5mm X2QFN thermally enhanced

package. The device is specified for operation across the

ambient temperature -40°C to +105°C.
