General Description
The DS3503 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
and feature an output voltage range of up to 15.5V. In
addition, both potentiometer outputs 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.
