ISL24211

The ISL24211 is an 8-bit programmable current sink that can be

used in conjunction with an external voltage divider to generate a

voltage and ground. The current sink’s full-scale range is

can be controlled between any arbitrary voltage range. The

ISL24211 has an 8-bit data register and 8-bit EEPROM for storing

interface to read and write to the register and EEPROM. After the

power-up the EEPROM contents are automatically transferred to

the data register, and the pre-programmed output voltage

appears on the VCOM_OUT pin.

The ISL24211 also features an integrated, wide-bandwidth, high

input of an LCD panel.

The ISL24211 is available in an 10 Ld 3mm x 3mm TDFN

package. This package has a maximum height of 0.8mm for very

low profile designs. The ambient operating temperature range is
