The AD8402AR100 is a dual-channel digital potentiometer from Analog Devices, part of the AD8400/AD8402/AD8403 family. It features 256-position variable resistance with a total resistance of 100kOhm and a linear taper. The device is controlled via a 3-wire SPI-compatible serial interface, supporting data loading rates up to 10 MHz.
This digital potentiometer operates from a single 2.7V to 5.5V supply and is specified over the -40°C to +125°C temperature range. It offers a typical temperature coefficient of 500ppm/°C. The volatile memory type means the wiper position is reset on power-up.
The AD8402AR100 is housed in a 14-lead SOIC surface-mount package (0.154" width, 3.90mm body width). It is suitable for applications such as mechanical potentiometer replacement, programmable filters, volume control, and power supply adjustment. The device is qualified for automotive applications.
