AD8403AR10-REEL Digital Potentiometer

The AD8403AR10-REEL from Analog Devices Inc. is a high-performance digital potentiometer that offers a compact and precise solution for adjusting and controlling voltages in electronic circuits. This integrated circuit (IC) is part of the AD8400/AD8402/AD8403 series, which provides a single/dual/quad channel configuration, respectively. The AD8403AR10-REEL specifically is a quad-channel device, providing four independent variable resistors in one package, making it an ideal choice for applications requiring multiple adjustments or settings.

This digital potentiometer has a resistance value of 10 kΩ, which can be digitally controlled through a 3-wire serial interface. It allows for 256 positions, giving designers the ability to finely tune resistance with a resolution of approximately 0.4% per step. This level of control is particularly useful in applications such as gain control, filter adjustment, or calibration of systems where precision is key.

The AD8403AR10-REEL comes in a surface-mount package and is supplied on a reel, which is suitable for automated assembly processes, making it convenient for mass production environments. The device operates over a wide voltage range, typically from 2.7V to 5.5V, and features a temperature coefficient of 5 ppm/°C, ensuring stable performance across varying temperatures.

One of the standout features of this digital potentiometer is its non-volatile memory (EEPROM), which allows the resistance setting to be saved even when the power is turned off. This means that the device can retain its last position upon power-up, which is critical for applications that require consistent settings between power cycles.

The AD8403AR10-REEL is designed to be robust and reliable, with a typical endurance of 1 million cycles and data retention of 50 years. These characteristics make it an excellent choice for long-term applications in industrial control, automotive systems, and consumer electronics where durability and reliability are paramount.

With its precision, programmability, and reliability, the AD8403AR10-REEL digital potentiometer from Analog Devices Inc. is a versatile component that can meet the needs of a wide array of electronic designs.
