Overview

The DS1841N+ is a temperature controlled, non-volatile, I²C logarithmic resistor in 10 pin TDFN package. It has an on-chip temperature sensor and associated analogue to digital converter (ADC). The integrated temperature sensor indexes a 72 byte NV lookup table (LUT). The LUT output can drive the resistor directly or be added to an NV initial-value register (IVR) to drive the resistor. This flexible architecture allows the DS1841N+ to provide a temperature-compensated resistor output with arbitrary slope. Programming is accomplished by an I²C-compatible interface which can operate at speeds of up to 400kHz.
