Working Principle

The ISL23445WFRZ-TK digital potentiometer is based on a hardware multiplier block, which consists of two digital-to-analog converters, one N-way analog switch, and a 3-way multiplexer. The N-way analog switch is used to select which resistor values are supplied to the multiplexer. The multiplexer then forwards the selected resistances to the resistive network, which adjusts the resistance of its output.

The resistance of the output is controlled by the two digital-to-analog converters. The first DAC sets the reference voltage, while the second DAC sets the resistance value. The combination of the two DACs allows the ISL23445WFRZ-TK to adjust the resistance value with a resolution of 0.01 Ohm. In addition, the ISL23445WFRZ-TK has a low-noise design, which helps to ensure accurate data acquisition.

The ISL23445WFRZ-TK also features an integrated I2C bus. This bus allows the user to adjust the resistance value remotely through an I2C compatible microcontroller. The I2C interface also allows the user to monitor the potentiometer’s current resistance value, making it ideal for use in systems that require precise control.
