ISL24201

The ISL24201 provides an 8-bit programmable current sink that is used in conjunction with an external voltage divider and buffer amplifier to generate a voltage source that is positioned between the analog supply voltage and ground. The current sinks resolution is controlled by an external resistor, R_SET, and the span of the V_COM voltage is controlled by the voltage divider resistor ratio and the source impedance of R₁ and R₂. This device has an 8-bit data register and 8-bit EEPROM for storing a volatile and a permanent value for its output. The ISL24201 has an I²C bus interface that is used to read and write to its registers and EEPROM. At power-up the EEPROM value is transferred to the data register and output. The ISL24201 is available in an 8 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.
