LM1971, Digitally Controlled 62dB Audio Attenuator
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 exhibite
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 DIP or SO packages. The LM1971 is controlled by a TTL/CMOS compatible 3-wire serial digital interface. The active low LOAD line e
