DS3502

High-Voltage NV I²C Potentiometer

Low-Cost Potentiometer


Please check latest availability status for a specific part variant.

Description

The DS3502 is a 7-bit, nonvolatile (NV) digital potentiometer featuring an output voltage range of up to 15.5V. Programming is accomplished by an I²C-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.
