The ISL24212 is an 8-bit programmable current sink that can be used in conjunction with an external voltage divider to generate a voltage source (VCOM) positioned between the analog supply voltage and ground. The current sinks full-scale range is controlled by an external resistor, RSET. With the appropriate choice of external resistors R1 and R2, the VCOM voltage range can be controlled between any arbitrary voltage range. The ISL24212 has an 8-bit data register and 8-bit EEPROM for storing both a volatile and a permanent value for its output, accessible through a single up/down counter interface pin (CTL). After the part is programmed with the desired VCOM value, the Counter Enable pin (CE) can be grounded to prevent further changes. On every power-up, the EEPROM contents are automatically transferred to the data register and the pre-programmed output voltage appears at the VCOM_OUT pin. The ISL24212 also features an integrated, wide-bandwidth, high output drive buffer amplifier that can directly drive the VCOM input of an LCD panel. The ISL24212 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.
