This is a 7 bit digital potentiometer with non-volatile memory. It features an output range of up to 15.5V. Programming is done through an I2C interface, with operating speeds of up to 400kHz. There are 2 ports RL and RH to decide the potentiometer limits.

Its key features are:
> 10k ohms of full scale resistance
> I2C compatible interface
> Operating temperature range of -40 to +100 degree Celsius
> Digital operating voltage of 2.5 to 5.5 V
> Analog operating voltage of 4.5 to 15.5V
> Up to 4 DS3502s can share the same I2C bus
> Compact 10 pin micro SOP package
> On chip temperature sensor and ADC
> Has a 36 byte look up table

Some of its applications are:
> T-LCD VCOM calibration
> Instrumentation and industrial controls
> Mechanical POT replacement
