The AD8400ARZ100 is a single-channel, 256-position digitally controlled variable resistor (VR) from Analog Devices. It is designed to replace mechanical potentiometers in a wide range of applications, offering precise digital adjustment of resistance via a 3-wire SPI-compatible serial interface.
Key electrical specifications include 100 kOhms end-to-end resistance with a ±30% tolerance, linear taper characteristic, and a typical temperature coefficient of 500 ppm/°C. The device operates from a single 2.7V to 5.5V supply and has a volatile memory type, meaning the wiper position is reset at power-up.
The IC is housed in an 8-pin SOIC surface-mount package (8-SOIC, 0.154" width) with a supplier device package designation of 8-SOIC. It is rated for an operating temperature range of -40°C to +125°C, suitable for industrial and automotive environments.
