Data Acquisition - Digital Potentiometers are used for electrical control and transduction for many devices and electronic systems. The ISL90728UIE627Z-TK is a perfect example of an advanced digital potentiometer used to facilitate control and accurate measurement of voltage in various industrial applications. The device is ideal for applications that require highly precise control while also benefiting from a large range of operational voltage.

The ISL90728UIE627Z-TK is a three terminal, non-volatile digital potentiometer with a wiper current limit of 10mA. It is powered by a single supply voltage between 1.2V and 3.6V, and is available in an 8-pin TSSOP package. The device is engineered with robust features, such as a wiper lock which prevents unintentional settings of the wiper during operation and a low power consumption of 110uA, making it the ideal choice for applications where accurate control and low power consumption is essential.

The ISL90728UIE627Z-TK is designed for use in wide range of applications such as digital audio volume control, digital LCD display brightness control, motor speed/ position control, gain control and so on. The operating principle of the device is based on the concept of resistance-dividers where the wiper is used to set the resistance value of a voltage divider. When the wiper position of the potentiometer is changed, the resistance changes which allows adjustment of the output voltage.

To adjust the wiper position and the output voltage, the ISL90728UIE627Z-TK utilizes a simple serial input interface. The interface is a 3-wire SPI 4-wire SPI bus which uses up to 4 bits of control data to set the wiper position. This interface allows the device to be remotely controlled and adjusted, making it suitable for applications that require control over a long distance. The device also has a non-volatile memory which is used to store wiper settings, making it ideal for applications which need to retain settings even when powered down.

The ISL90728UIE627Z-TK offers an exceptional level of accuracy and performance with a potentiometer resolution of up to 256 steps and a linearity of 0.1% from 0 to 85 degrees Celsius. Additionally, the device is designed with short circuit protection, temperature protection and electrical noise prevention, making it a durable, reliable and secure choice for industrial applications. Its small size and low heat output make it suitable for compact spaces, and its low power consumption makes it an incredibly efficient choice for applications that require longterm operation.

The ISL90728UIE627Z-TK offers a comprehensive solution to applications that require advanced control and precise sensing of voltage levels. With its robust performance and variety of features, it is a perfect choice for use in industrial applications where accuracy, reliability, security and complex control functions are required.
