Renesas Electronics Corporation Programmable V_COM Calibrator with EEPROM and Output Buffer ISL24211IRTZ-T13

The ISL24211 is an 8-bit programmable current sink that can be used in conjunction with an external voltage divider to generate a voltage source (VsubCOM/sub) positioned between the analog supply voltage and ground. The current sink's full-scale range is controlled by an external resistor, RsubSET/sub. With the appropriate choice of external resistors Rsub1/sub and Rsub2/sub, the VsubCOM/sub voltage range can be controlled between any arbitrary voltage range. The ISL24211 has an 8-bit data register and 8-bit EEPROM for storing both a volatile and a permanent value for its output, with an Isup2/supC interface to read and write to the register and EEPROM. After the part is programmed, the Isup2/supC interface is no longer needed; on power-up the EEPROM contents are automatically transferred to the data register, and thebrpre-programmed output voltage appears on the VCOM_OUT pin.brbr The ISL24211 also features an integrated, wide-bandwidth, high output drive buffer amplifier that can directly drive the VsubCOM/sub input of an LCD panel.brbr 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 -40°C to +85°C.
