Analog Devices AD5274BCPZ-100-RL7 is a single-channel, 256-position digital rheostat belonging to the AD5272/AD5274 family. It offers a nominal resistance of 100 kOhms with a maximum ±1% end-to-end tolerance error and a typical temperature coefficient of 5 ppm/°C. The device is controlled via an I2C-compatible interface and incorporates 50-times programmable (50-TP) non-volatile memory to store wiper positions.
The rheostat operates from a single supply of 2.7 V to 5.5 V or a dual supply of ±2.5 V to ±2.75 V, making it suitable for both DC and AC/bipolar applications. The operating temperature range is -40°C to +125°C. The selectable address feature allows multiple devices to share the same I2C bus.
The AD5274 simplifies precision calibration and open-loop applications due to its low resistor tolerance error. Typical applications include replacing mechanical rheostats, variable gain control in op-amp circuits, instrumentation gain and offset adjustment, programmable filters, and sensor calibration.
The device is supplied in a surface-mount 10-lead LFCSP package measuring 3 mm × 3 mm with an exposed pad (10-LFCSP-WD). Based on available data, the moisture sensitivity level is MSL 1 (unlimited), but this information is unverified.
