Analog Devices AD5246 Digital Resistor Data Sheet
The AD5246 provides a compact SC70‑6 packaged solution for 128‑position resistance adjustment. It offers four end‑to‑end resistance options (5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ) and operates from a single 2.7 V‑5.5 V supply. An I2C‑compatible two‑wire interface allows full read/write access to the wiper register, with a power‑on preset to midscale.
Operation is based on a 7‑bit RDAC register that selects one of 128 taps. The device includes ESD protection, level‑shifting guidance for mixed‑voltage systems, and a recommended power‑up sequence (GND, VDD, digital inputs, then VB/VW). Current through the wiper is limited to 5 mA continuous (20 mA pulse) to protect the internal switches.
