AD8403ARUZ50 Description

The AD8403ARUZ50 is a digital potentiometer from Analog Devices Inc., designed for precision control in a variety of electronic applications. This device features a 50kΩ resistance with a tolerance of ±30%, making it suitable for applications requiring adjustable resistance. The AD8403ARUZ50 operates within a supply voltage range of 2.7V to 5.5V, ensuring compatibility with a wide range of power supplies. It has a temperature coefficient of 500ppm/°C, which ensures stable performance across varying temperature conditions.

The AD8403ARUZ50 is configured as a potentiometer with 256 taps, providing fine control over resistance settings. It features a linear taper, which means the resistance changes proportionally with the tap position, making it ideal for applications requiring precise adjustments. The device also includes a cascade pin, which allows multiple potentiometers to be connected in series for extended range or more complex configurations.

The AD8403ARUZ50 uses an SPI interface for communication, enabling easy integration with microcontrollers and other digital systems. It is housed in a 24-lead TSSOP package, which is suitable for surface-mount applications, ensuring it can be easily integrated into compact designs. The device is REACH unaffected and RoHS3 compliant, making it suitable for environmentally conscious designs. It also has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure to ambient conditions before assembly.
