The ISL90462UIE627Z-TK is an industrial grade digital potentiometer, belonging to the family of data acquisition systems with a voltage range of 1.8V to 5.5V. The device is ideally suited for applications where precise linear DC control of critical parameters is needed and is particularly suited to automotive and industrial applications.

Digital potentiometers are resistors with a wiper that can be adjusted electronically, via a digital code. The wiper is moved in discrete steps and each step position is assigned a value. The full-scale value of the device is set by the user and the adjustment value can be set to the full-scale value. The ISL90462UIE627Z-TK is capable of producing an adjustable output voltage range of 0V to 24V, with a maximum resolution of 16 bits. Overcurrent and overtemperature protection provide safe and reliable operation.

Due to its high resolution, the ISL90462UIE627Z-TK is ideal for monitoring and controlling applications that require precise analog control such as voltage regulation for automotive and industrial power supplies. It is also suited for applications that require precise linear control such as PWM motor control, audio adjustment, and medical instrumentation. It can be used to adjust the gain of sensors, components in signal conditioning circuits, and even as replacements for resistors in electronic circuits.

The ISL90462UIE627Z-TK is equipped with SPI and I2C interfaces, which provides for ease of communication with a host microcontroller. The device is operated with a 3-wire interface that comprises the power supply, ground supply and logic signals. The I2C or SPI protocol is selected by the logic pins. If a microcontroller requires that the digital potentiometer be set to a certain output voltage or resistance, it transmits its commands over the I2C or SPI bus. The digital potentiometer then translates the commands and adjusts its output voltage or resistance accordingly.

The ISL90462UIE627Z-TK has a temperature range of −40 °C to +125 °C and can operate from −40 °C to +75 °C without any external cooling. It is made up of a combination of resistors, microprocessor, and wiper tracks, arranged in a resistive ladder network. The device is designed to provide high accuracy and resolution, to adjust the output resistance precisely and accurately over a wide range of conditions. It also has a fast response time, which makes it suitable for applications where fast adjustments are necessary.

The ISL90462UIE627Z-TK has multiple protection features, such as over-current protection, over temperature protection and short-circuit detection that can limit current supply during fault conditions. It is also EMC compliant, providing protection from electro-magnetic fields due to its construction.

The ISL90462UIE627Z-TK is suitable for applications that require high performance, accuracy, and flexibility. The device is easy to program and configure, and can be used with a host microcontroller that supports I2C and SPI protocols. It is highly robust, reliable, and can handle extreme temperature conditions.
