DS1881規(guī)格書詳情

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).

Features

? Dual, Audio Log Taper Potentiometers

? Low THD+N and Crosstalk

? 5V Analog Supply (Independent of Digital Supply)

? 3V to 5V Digital Supply Range

? Potentiometer Settings Configurable as NV or Volatile

? Zero-Crossing Detector Eliminates Switching Noise

? Two User-Configurable Attenuation Options

? Configuration Option 1: 63 Positions Provide 1dB Attenuation Steps from 0dB to -62dB Plus Mute

? Configuration Option 2: (Software-Compatible with the DS1808): 33 Positions Plus Mute as Follows

??? Positions 0–12: 1dB per Step for 12 Steps

??? Positions 13–24: 2dB per Step for 12 Steps

??? Positions 25–32: 3dB per Step for 8 Steps

? I2C*-Compatible Serial Interface

? Three Address Pins Allow Up to 8 Devices on I2C Bus

? 45k? Potentiometer End-to-End Resistance

? Industrial Temperature Range (-40°C to +85°C)

? 16-Pin TSSOP or SO Package

Applications

??? Notebook and PC Audio

??? Portable Audio Equipment

??? Car Stereo

??? Consumer Audio/Video
