CAUTION: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device (at these or any other conditions above those listed in the operational sections of this specification) is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe Intersil ISL23711 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, and a control section. The wiper position is controlled by an I2C interface.
The potentiometer ISL23711 is implemented by a resistor array composed of 127 resistive elements and a wiper switching network. The wiper terminal can be connected to either end of the resistor array or at any one of the Tap Positions in between, providing 128 steps of resolution between RL and RH. The "position" of the wiper ISL23711 is determined by the value assigned to the volatile Wiper Register (WR). The WR can be directly written to and read from using standard I2C interface protocol. The ISL23711 is available in either a 10k or 50k version.
The ISL23711 can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including:
• Industrial and Automotive Control
• Parameter and Bias Adjustments
• Amplifier Bias and Control
