The Texas Instruments LM1971M/NOPB is a digitally-controlled single-channel audio attenuator fabricated on a CMOS process. It provides variable attenuation in 1 dB steps from 0 dB to -62 dB, with a mute function offering over 100 dB of attenuation. The device is designed for click and pop-free attenuation changes.
Key specifications include a low Total Harmonic Distortion (THD) of 0.0008% and a Dynamic Range of 115 dB, making it suitable for digital audio applications. The frequency response is greater than 200 kHz (-3 dB).
This audio attenuator operates over a temperature range of -40°C to 85°C and is controlled via a TTL/CMOS compatible 3-wire serial digital interface. It is available in an 8-pin SOIC package suitable for surface mounting.
The LM1971M/NOPB is designed for applications requiring precise audio level control without introducing audible artifacts. Its specifications make it a good choice for various communication systems and general audio processing needs.
