The AD8402AN10 is a dual-channel, 256-position digital potentiometer from Analog Devices, part of the AD8400/AD8402/AD8403 family. It replaces mechanical potentiometers in applications requiring precise digital adjustment. Each channel provides a 10kΩ end-to-end resistance with a linear taper, controlled via a 3-wire SPI-compatible serial interface supporting up to 10 MHz data rate.
Operating from a single 2.7V to 5.5V supply, the device is qualified for automotive applications and operates over the -40°C to +125°C temperature range. It features a power shutdown mode drawing less than 5 μA. The resistance tolerance is ±20% with a typical temperature coefficient of 500 ppm/°C. Memory is volatile, requiring initialization on power-up.
Packaged in a 14-DIP (0.300", 7.62mm) through-hole package with 14-PDIP supplier package, the AD8402AN10 is suitable for prototyping and integration into designs requiring dual digital potentiometer functionality. Typical applications include mechanical potentiometer replacement, programmable filters, volume control, line impedance matching, and power supply adjustment.
The device operates from 2.7V to 5.5V single supply.
It is available in a 14-DIP (0.300", 7.62mm) through-hole package, also referred to as 14-PDIP.
The operating temperature range is -40°C to +125°C.
It is listed as RoHS3 compliant, but this status is unverified.
It has 256 taps per channel.
It uses a 3-wire SPI-compatible serial interface.
The memory is volatile, so the wiper position must be set on power-up.
