音频增益控制用数字电位器

资料介绍
摘要:数字电位器(盆)提供音频音量(增益)控制应用的优势,可以取代笨重的机械电位器,尤其是在手持便携设备,如MP3播放器,掌上电脑,手机,移动互联网设备,或立体声调幅/调频收音机。本文档介绍了音频控制,如对数锥盆(日志盆)提供的数字电位器的类型。它会检查使用日志锥盆和音频放大器的几种常见的设计,评估他们的优点和缺点,并建议电路设计。

Audio Gain Control Using Digital Potentiometers


Abstract:Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky
mechanical pots, especially in handheld portable devices such as MP3 players, PDAs, cell phones, mobile Internet devices, or
stereo AM/FM radios. This document describes the types of digital pots available for audio control such as logarithmic taper pots
(log pots). It examines sev……
