The DS3502 is a 7-bit, nonvolatile (NV) digital poten-
tiometer (POT) featuring an output voltage range of up to
15.5V. Programming is accomplished by an I
ible 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.
