General Description
The DS1881 is a dual, nonvolatile (NV) digital potentiometer designed to operate in audio systems that require 5V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. The DS1881 has separate supplies for the potentiometers (VCC) and the communication circuitry (VDD).
