LM1971 Overture Audio Attenuator Series Digitally Controlled 62 dB Audio Attenuator with Mute May 1999 LM1971Overture™ Audio Attenuator Series Digitally Controlled 62 dB Audio Attenuator with/Mute General Description The LM1971 is a digitally controlled single channel audio attenuator fabricated on a CMOS process.
Attenuation is variable in 1 dB steps from 0 dB to −62 dB.
A mute function disconnects the input from the output, providing over 100 dB of attenuation.
The performance of the device is exhibited by its ability to change attenuation levels without audible clicks or pops.
In addition, the LM1971 features a low Total Harmonic Distortion (THD) of 0.
0008%, and a Dynamic Range of 115 d...
