The AD5258 is a nonvolatile, I2C-compatible 64-position digital potentiometer with compact packaging and multiple features, suitable for applications such as LCD panel adjustment, power supply adjustment, and RF amplifier biasing.
The AD5258 provides a 64‑position digital potentiometer in a small MSOP‑10 package, offering non‑volatile memory to retain wiper settings after power‑off. It features an I2C‑compatible interface, a VLOGIC pin for flexible operation, and address pins AD0/AD1 that allow up to four devices on a single bus.
The device operates from a 2.7 V to 5.5 V supply, supports a wide temperature range (‑40 °C to +85 °C), and includes specifications such as 0.1 % resistance tolerance, 100‑year data retention at 55 °C, and low supply currents for power‑efficient designs.
