The ISL23418TFUZ is a dual-channel, non-volatile digital potentiometer manufactured by Intersil Corporation. It is designed specifically for data acquisition applications where precision is of utmost importance. It provides a wide range of programmable resistances, allowing the user to precisely control a given application. Furthermore, it features thermal monitoring and protection, allowing the device to be used in extreme environments.

The ISL23418TFUZ consists of two programmable channels, each containing a fixed, non-volatile ceramic resistor. The resistance value of each channel is determined by the number of bits and the digital code, which is stored on an EEPROM. With the device providing a wide range of resistance depth, it can be used to accurately control the voltage output of complex power supplies and devices. Furthermore, the digital potentiometer can be used in Real-Time Operating System (RTOS) and programmable logic devices, making it a suitable component for applications such as automotive, industrial, and medical.

In terms of its working principle, the ISL23418TFUZ operates by forming a voltage divider circuit with its two channels. The output of each channel is determined by the voltage drops created by the integrated resistors. The resistors’ resistance is determined by the digital code stored on the device’s EEPROM. This code can be adjusted via programming, allowing the user to control the voltage output of his or her application.

To ensure that the device operates accurately, Intersil employs over-temperature and over-voltage protection. The device takes in an operating temperature between -25°C to +85°C, as well as a nominal voltage supply of 3.3 V to 5.5 V. Furthermore, it also incorporates a power-on reset circuit, ensuring that the digital potentiometer is reset properly whenever it is powered on.

In order to maximize the potential of the ISL23418TFUZ, Intersil offers a Digital Potentiometer Evaluation Kit (DEK). It contains the digital potentiometer, a power supply, a programming cable, a potentiometer wheel and several other components. The kit is designed to provide a basic understanding of the digital potentiometer and provides a platform for the evaluation of the device.

The ISL23418TFUZ is an advanced, non-volatile digital potentiometer specifically designed for data acquisition applications. It is programmed by storing a digital code on its EEPROM and features protection against over-temperature and over-voltage conditions. Furthermore, the device is supported by Intersil’s DEK, providing a platform for device evaluation. Therefore, it is a suitable component for a wide range of applications such as automotive, industrial, and medical.
