Maxim DS1847 Dual Temperature-Controlled Variable Resistor Datasheet
The DS1847 integrates two 256‑position linear variable resistors (10 kΩ or 50 kΩ) with a direct‑to‑digital temperature sensor. Resistor values are stored in EEPROM and accessed via a standard 2‑wire I²C‑compatible interface, allowing temperature‑compensated bias settings with minimal external circuitry.
The device operates from 3 V to 5.5 V and functions over a temperature range of –40 °C to +95 °C. It is available in 14‑pin TSSOP and 16‑ball CSBGA packages, and supports programming of lookup tables to define resistance versus temperature curves.
