ISL24822 Functional Diagram
描述
Support is limited to customers who have already adopted these products.
The ISL24822 is a programmable 14-Channel, 10-bit reference voltage generator with a digitally-controlled VCOM Calibrator 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.
