The Texas Instruments LM1972MX/NOPB is a digitally controlled, 2-channel audio attenuator designed for consumer and professional audio applications. It offers a wide attenuation range of up to 78 dB, with fine 0.5 dB steps for precise volume control. A dedicated mute function provides a minimum attenuation of 96 dB, ensuring pop-free transitions.
Key performance specifications include a total harmonic distortion plus noise (THD+N) of only 0.003% (max), a frequency response up to 100 kHz (-3dB min), and an excellent signal-to-noise ratio of 110 dB (min). High channel separation of 100 dB (min) is also achieved.
This device operates from a 4.5V to 12V supply and features a 3-wire serial interface (SPI) for easy control and daisy-chaining capabilities. It is housed in a 20-SOIC surface-mount package, measuring 12.8 mm x 10.3 mm.
The LM1972MX/NOPB is suitable for applications requiring precise audio level control with minimal signal degradation.
