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

Product Status: Mass Production

OVERVIEW

The ISL24813 is an I2 C 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 I2 C interface.

ISL24813 is available in a 32 Ld TQFN package and is specified for operation over the
-40°C to +85°C temperature range.
