Programmable 18-Channel x 2 Bank, 10-Bit TFT-LCD VREF Generator with Buffered VCOM Calibrator

The ISL24813 is an I2C programmable 18-channel, 10-bit reference voltage generator with a digitally controlled VCOM calibrator and op amp. Two selectable banks of 18 channels allow fast hardware or software switching between two different gamma curves. The ISL24813 is configured and controlled via a standard I2C interface.
ISL24813 is available in a 32 Ld TQFN package and is specified for operation across the -40°C to +85°C temperature range.
