FEATURES
DESCRIPTION
The LM1972 is a digitally controlled 2-channel 78dB
2
3-Wire Serial Interface
audio attenuator fabricated on a CMOS process.
Daisy-Chain Capability
Each channel has attenuation steps of 0.5dB from
104dB Mute Attenuation
0dB–47.5dB, 1.0dB steps from 48dB–78dB, with a
mute function attenuating 104dB. Its logarithmic

can
be
customized
through
software to fit the desired application.
APPLICATIONS
The performance of a
μPot is demonstrated through
Automated Studio Mixing Consoles
its excellent Signal-to-Noise Ratio, extremely low
Music Reproduction Systems
(THD+N), and high channel separation. Each
μPot
Sound Reinforcement Systems
contains a mute function that disconnects the input

from
the
output,
providing
a

of
