The AD8403ARZ1 is a quad-channel, 256-position digital potentiometer from Analog Devices, designed to replace mechanical potentiometers and variable resistors in electronic circuits. It offers a nominal resistance of 1 kOhm with a maximum resistor tolerance of 20% (per manufacturer page) and a typical temperature coefficient of 500 ppm/°C.
This device operates from a single 2.7V to 5.5V supply and features a 3-wire SPI-compatible serial interface for digital control. It includes a cascade pin for daisy-chaining multiple devices. The AD8403ARZ1 provides a typical bandwidth of 5 MHz and low total harmonic distortion of -90 dB, making it suitable for audio and signal conditioning applications.
The potentiometer is housed in a 24-SOIC (0.295", 7.50mm Width) surface-mount package with an operating temperature range of -40°C to 125°C. Its volatile memory type requires re-initialization on power-up. Common applications include programmable filters, volume control, power supply adjustment, and line impedance matching.
