Product Summary

The LM1971M 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. The applications of the LM1971M include Communication systems, Cellular Phones and Pagers, Personal computer audio control, Electronic music (MIDI), Sound reinforcement systems, Audio mixing automation.
