Maxim DS1805 Addressable Digital Potentiometer Datasheet
The DS1805 digital potentiometer provides a single 256‑position resistor array that can be controlled via a 2‑wire serial bus. Up to eight devices can share the same bus using three address inputs, making it suitable for compact, multi‑device designs.
It is offered in 14‑pin TSSOP and 16‑pin SO packages, operates from 2.7 V to 5.5 V, and is specified for an industrial temperature range of –40 °C to +85 °C. The device includes a volatile SRAM register and supports both standard (100 kHz) and fast (400 kHz) bus modes.
