Product 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 DS1841 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.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 100°C
- 22Kohm to 3.7Kohm adjustable logarithmic resistor with a 3.6Kohm fixed resistor
- 128 wiper tap points
- End to end resistance is 22Kohm at ±20% tolerance and temperature coefficient is 250ppm/°C
