ISL24822: Programmable 14-Channel x 2 Bank, 10-bit TFT-LCD VREF Generator with Buffered VCOM Calibrator

The ISL24822 is a programmable 14-Channel, 10-bit reference voltage generator with a digitally-controlled VCOMCalibrator and op amp. Two selectable banks of 14 channels allow fast hardware or software switching between 2 different gamma curves. The ISL24822 is configured and controlled via a standard I2C Interface.

The ISL24822 is available in a 32 Ld TQFN package and is specified for operation over the -40°C to +85°C temperature range.
