The AD8403AR10-REEL is a quad-channel digital potentiometer from Analog Devices. It integrates four independent variable resistors with 256 tap positions each, configured as a linear-taper potentiometer. The total end-to-end resistance is 10 kΩ with ±20% tolerance. It uses an SPI-compatible 3-wire serial interface for digital control, with a 10 MHz data update rate.
This device operates from a single 2.7V to 5.5V supply and is designed for replacing mechanical potentiometers in precision adjustment applications. The wiper position is maintained in volatile memory, requiring the serial register to be reloaded after power-up. Quiescent current is 10 nA typical, and shutdown current is less than 5 μA, supporting low-power designs.
The AD8403AR10-REEL is offered in a 24-lead SOIC-W (wide) surface-mount package, measuring 0.295" (7.50 mm) width. It operates over an industrial temperature range of -40°C to +125°C and exhibits a temperature coefficient of 500 ppm/°C. Applications include programmable filters, volume/panning controls, line impedance matching, and power supply adjustments.
