The AD8403ARU10 is a quad-channel, 256-position digital potentiometer from Analog Devices. It offers a nominal resistance of 10kΩ with ±20% tolerance in a linear taper configuration. The device operates from a single 2.7V to 5.5V supply and features a 3-wire SPI-compatible serial interface with a 10 MHz update rate. It includes a cascade pin for daisy-chaining multiple devices.
This digital potentiometer replaces traditional mechanical potentiometers in applications requiring precise, programmable resistance adjustment. With 256 taps per channel, it provides fine resolution for volume control, filter tuning, and power supply trimming. The volatile memory type means the wiper position is reset on power-up.
The AD8403ARU10 is packaged in a surface-mount 24-TSSOP (4.40mm width) package, suitable for automated assembly. It has an operating temperature range of -40°C to 125°C and a typical temperature coefficient of 500 ppm/°C. The shutdown supply current is less than 5 μA, making it suitable for power-sensitive designs.
