| Description | Pot3-Channel 76dB Audio Attenuator |
|
|
The LM1973 is a digitally controlled 3-channel 76dB audio attenuator fabricated on a CMOS process. Each channel has attenuation steps of 0.5dB from 0dB 15.5dB, 1.0dB steps from 16dB 47dB, and 2.0dB steps from 48dB 76dB, with a mute function attenuating 104dB. Its logarithmic attenuation curve can be customized through software to fit the desired application.
