Working Principle of ISL23315WFUZ

The working principle of ISL23315WFUZ is based on the principle of digital potentiometry. Digital potentiometers are multi-bit digital devices that are used to control the resistance level of a signal. In ISL23315WFUZ, a digitally adjustable resistor is connected between two adjustable analog voltage supplies. The user controls the resistance level of the potentiometer by setting the digital input words.

ISL23315WFUZ combines the digitally adjustable resistor and the buffer amplifier in a single high performance device. The adjustable resistor is composed of four digitally adjustable resistor elements, each containing eight segments. The four digital bits that control each segment determine the resistance between the two voltage supplies.

The buffer amplifier is connected to the output of the digitally adjustable resistor. The buffer amplifier amplifies the signal from the adjustable resistor, providing a higher output voltage. The output voltage is proportional to the input voltage and the resistance of the digitally adjustable resistor.
