Overview
DS1882 Rev 0; 6/06 Dual Log Audio Digital Potentiometer General Description The DS1882 is a dual, nonvolatile (NV) digital potentiometer designed to operate in audio systems that accomodate 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 communication circuitry (VDD).
For clickless/popless operation, a zero-crossing detector allows the wiper position to change when there is no voltage across the potentiometer.
The DS1882 is also designed to minimize crosstalk, and the two digital potentiometers provide 0.
5dB channel-to-channel matching to pr...
