The AD5144BRUZ100 is a high-performance, digital potentiometer with a maximum resistance rating of 100 kΩ. This digital potentiometer offers a very low power consumption with a supply current of 1 µA, enabling it to be well suited for low power applications. This component is configured to provide a unique resistance value with 12-bit resolution and unlimited resistance taps, allowing it to remain stable under extreme environmental conditions.

The AD5144BRUZ100 is an ideal solution for high precision adjustable gain and offset adjustment in audio and automotive systems. It provides the ability to adjust the audio or electrical levels of an application without making an undesirable audible noise or providing an distortions. Additionally, it has the capability to provide a wide range of adjustable gain and offset control both in AC and DC applications.

The digital potentiometer also has various application fields, such as brightness display management, temperature control, digital control systems, and in instrumentation control. To ensure accurate performance, it is designed for 95% non-volatile memory and a guaranteed total resistance tracking tolerance. The excellent non-volatile memory enables the device to remember settings, even when current supply is interrupted.

The AD5144BRUZ100 is a single chip solution that combines both a digital potentiometer and a terminal resistor in one package. It is a digitally controlled, three-terminal device with a control input pin and two resistive element pins. The control pins activate stored resistance tap settings that adjust the output voltage of the device. It is also capable of providing a zero resistance difference between the two output pins, meaning that it can act as a voltage divider circuit and offer precise adjustable gains.

The AD5144BRUZ100 working principle is based on the combination of a digitally controlled oscillator and a resistor matrix, which splits the full range of resistance into multiple tap points. Once the tap point is selected, a predefined resistance is placed between two output pins. The device is powered with an analog and digital voltage, and the digital control voltage determines at which points the resistor chain will be cut. The control pins also allow for precise resistance control, as the device can be programmed to set various resistance values, from as low as 0Ω to as high as 100 kΩ.

The AD5144BRUZ100 is a highly integrated digital potentiometer with many versatile applications, including audio and automotive systems. Its low power consumption and wide range of adjustable gains make the device a great choice for high precision control solutions. Furthermore, its non-volatile memory guarantees that settings will remain unchanged, even in the presence of power outages.
