The LM1972MX from Texas Instruments is a 2-channel audio attenuator fabricated on a CMOS process. This device, also known as a μPot, provides a typical attenuation range of 78 dB, with individual channel steps of 0.5 dB from 0 dB to 47.5 dB and 1.0 dB steps from 48 dB to 78 dB. It includes a mute function that offers a minimum attenuation of 96 dB, with a specified mute attenuation of 104 dB.
Key performance specifications include a maximum Total Harmonic Distortion + Noise (THD+N) of 0.003%, a minimum signal-to-noise ratio of 110 dB, and a minimum channel separation of 100 dB. The frequency response is specified at 100 kHz (−3dB) minimum. Transitions between attenuation settings are designed to be pop-free.
The LM1972MX features a 3-wire serial digital interface for control and supports daisy-chain capability. It is housed in a 20-pin SOIC (DW) package and operates within a temperature range of 0°C to 70°C. The logarithmic attenuation curve can be customized via software for specific application needs.
