    | Manufacturer: | National Semiconductor |  
    | Datasheet: | PDF (305K). Click here to download *) |  
    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 0dB15.5dB, 1.0dB steps from 16dB47dB, 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.  |
