概要
Description
The AD8403ARUZ10 is a dual, 256-position, digital potentiometer manufactured by Analog Devices. It features two independently controlled potentiometers in a single package, making it ideal for applications that require variable resistance. The device operates over a supply voltage range of 2.7V to 5.5V and communicates via a simple SPI interface, allowing easy integration into microcontroller-based systems.
Key features include low temperature drift, high accuracy, and non-volatile memory options (in some variants) that retain settings after power loss. The AD8403 is commonly used in applications like audio volume control, sensor calibration, and gain adjustment in amplifiers.
Its compact package (TSSOP-10) is suitable for space-constrained designs. The device's robust performance and versatility make it an excellent choice for both consumer electronics and industrial applications.
