DS1882 Overview
The DS1882 is a dual, nonvolatile (NV) digital potentiometer designed to operate in audio systems that acodate up to ±7V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. The DS1882 has separate supplies for the potentiometers (VCC) and the munication circuitry (VDD).
