LM1973 碌Pot 3-Channel 76dB Audio Attenuator with Mute

3-Channel 76dB Audio Attenuator with Mute
General Description
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鈥?5.5dB, 1.0dB
steps from 16dB鈥?7dB, and 2.0dB steps from 48dB鈥?76dB,
with a mute function attenuating 104dB. Its logarithmic at-
tenuation curve can be customized through software to fit
the desired application.
The performance of a 碌Pot
鈩?/div>
is demonstrated through its ex-
cellent Signal-to-Noise Ratio, extremely low (THD+N), and
high channel separation. Each 碌Pot contains a mute function
that disconnects the input signal from the output, providing a
minimum attenuation of 96dB. Transitions between any at-
tenuation settings are pop free.
The LM1973鈥檚 3-wire serial digital interface is TTL and
CMOS compatible; receiving data that selects a channel and
the desired attenuation level. The Data-Out pin of the
LM1973 allows multiple 碌Pots to be daisy-chained together,
reducing the number of enable and data lines to be routed
for a given application.
