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 dB, making it suitable for
digital audio needs. The LM1971 is available in both
8-pin plastic PDIP or SOIC packages.
The LM1971 is controlled by a TTL/CMOS compatible
3-wire serial digital interface. The active low LOAD
line enables the data input registers while the CLOCK
line provides system timing. Its DATA pin receives
serial data on the rising edge of each CLOCK pulse, allowing the desired attenuation setting to be
selected.
