DS3501U+ (MAXIM INTEGRATED PRODUCTS)

The DS3501U+ is a high voltage, non-volatile I?C 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 I?C 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.
