14-Channel Programmable Gamma Buffer Evaluation Board


The ISL76534EVAL1Z is a complete platform for the evaluation on all datasheet specifications and functionalities of the programmable gamma buffer. The ISL76534 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 an internal EEPROM to store all reference voltage data. The EEPROM features an endurance of 10,000 write cycles and a data retention of 20yrs at 105°C.

The ISL76534EVAL1Z board is intended to provide an evaluation platform for the 4mmx5mm X2QFN ISL76534 package, programmable gamma buffer.
