The DS3501U+ is a high voltage, non-volatile I2C potentiometer with temperature sensor and LUT in 10 pin μSOP package. It is a 7bit digital potentiometer featuring an output voltage range of 15.5V. Programming is accomplished by an I2C compatible interface which can operate at speeds of up to 400kHz. External voltages are applied at the RL and RH inputs to define the lowest and highest potentiometer outputs. DS3501 contains an on-chip temperature sensor and associated analogue to digital converter (ADC). The ADC output addresses a 36 byte non-volatile lookup table (LUT). The LUT output can drive the pot directly or be added to an initial value register (IVR) to drive the pot.
Supply voltage range is 2.7V to 5.5V

Single linear taper potentiometer
128 wiper tap points
Address pins allow four DS3501 devices to share the same I2C bus
Pin and software compatible with ISL95311 (default mode)
End to end resistance is 10Kohm at ±20% tolerance and temperature coefficient is 4ppm/°C
Temperature compensated potentiometer output with arbitrary slope
