The Texas Instruments LM1971MX 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. A dedicated mute function disconnects the input from the output, offering over 100 dB of attenuation.
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 extends beyond 200 kHz (-3 dB).
The device features a TTL/CMOS compatible 3-wire serial digital interface for control. It is designed to change attenuation levels without audible clicks or pops.
The LM1971MX is available in an 8-pin SOIC package suitable for surface mounting. The operating temperature range is -40°C to 85°C.
The attenuation range, excluding mute, is 62 dB.
The dynamic range is 115 dB.
The mute attenuation is 102 dB.
The operating temperature range is -40°C to 85°C.
The LM1971MX is available in an 8-SOIC package.
The total harmonic distortion is 0.0008% (typical).
