 Description |
|
|
The 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 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 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 device is available in either a 10kΩ or 50kΩ version.
The device 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
