摘要： DS1808双记录音频电位器设计要求低THD和串扰水平的应用提供卓越的音频性能。利用± 12V电源。它提供24V的信号摆幅能力泄漏到峰值。它简化了设计，允许被引用到地面的电位偏低。 Application Note 160 Using the DS1808 in Audio Applications www.maxim-ic.com Introduction The DS1808 Dual Log Audio Potentiometer was designed to provide superior audio performance in applications that require low levels of THD and cross-talk. By utilizing a ±12V supply, it offers 24Vpp of signal swing capability, and it simplifies your design by allowing the low side of the potentiometer to be referenced to ground. The DS1808 features 33 positions that provide attenuation from 0dB to 60dB, and a mute function that provides 90dB of attenuation. It is controlled by a 2-wire interface, which can address up to eight DS1808s on a single 2-wire bus. It is available ……
