The ISL90840UIV2027 is a highly integrated, low power, digital potentiometer system offering flexible, remote, and non-volatile trimming capabilities. It provides a three terminal (R1, R2, and W) potentiometer design with up to 32 taps and 64 specific wiper settings allowing precision and flexibility for a wide variety of applications.

The ISL90840UIV2027 is designed for applications that require small size, high accuracy, low power consumption, and non-volatile control. It is compatible with a wide range of digital control systems from low voltage to 5V logic, including multiple communication interfaces such as SPI, I2C, USB, and MDIO.

In the data acquisition category, the ISL90840UIV2027 is classified as a digital potentiometer. Without external components, the ISL90840UIV2027 offers a variety of useful features like tap and wiper settings that can be configured through its various interfaces or stored in its internal non-volatile memory. This feature eliminates the need to purchase and install external trim components.

The ISL90840UIV2027 operating principle is based on the voltage divider principle, which states that when a combination of resistors is connected in series or in parallel, the voltage drop across each of the resistors is proportional to the resistor\'s resistance. In the typical potentiometer, the voltage divider is connected in series, with R1 and R2 forming the series resistors and W forming the adjustable wiper contact.

In the case of the ISL90840UIV2027, when the resistors are connected in series, the voltage is divided along the entire series. The wiper is used to adjust the voltage output by shunting a portion of the series toward the desired point. The ISL90840UIV2027 also offers adjustable taps and additional wipers so that more than one voltage output can be obtained from the same set of resistors.

The ISL90840UIV2027 can be used in a variety of applications. It is commonly used in electronic meters, video and telecommunication equipment, motor control systems, data acquisition systems, and other industrial applications. It can also be used in automotive applications, including engine control and vehicle monitoring systems.

The ISL90840UIV2027 is designed to offer precision, low power consumption, and ease of use for a variety of applications. With its flexible configuration options, onboard non-volatile memory, and reliable performance, this digital potentiometer is an excellent choice for replacing traditional mechanical potentiometers in many applications.
