MAXIM INTEGRATED PRODUCTS  DS3503U+  非易失性数字电位器, 步进, 5 kohm, 双, I2C, 线性, ± 20%, 2.7 V

The is a non-volatile I²C stepper potentiometer in 10 pin µSOP package. It features two synchronized stepping digital potentiometers, one 7-bit potentiometer with RW as its output and another potentiometer with Y as its output. Both potentiometers reference the RH and RL terminals which can be stepped up and down by configuring the control registers. Programming is accomplished by an I²C compatible interface that can operate at speeds of up to 400KHz.
