Overview

The DS1881Z-050+ is a dual, non-volatile (NV) audio taper digital potentiometer in 16 pin NSOIC package. This device is a log taper potentiometer which is 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. DS1881Z-050+ 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. It minimizes crosstalk and the two digital potentiometers and provides 0.5dB channel to channel matching to prevent volume differences between channels. Total harmonic distortion (THD) is also minimal as long as the wiper drives a high-impedance load.
