Rev 2.00
October 30, 2014 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 -40В°C to +85В°C
temperature range.
