The LM1971MX/NOPB from Texas Instruments 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 more than 100 dB of attenuation.
This audio attenuator is designed for click and pop-free attenuation changes, making it suitable for high-fidelity audio applications. Key specifications include a low Total Harmonic Distortion (THD) of 0.0008% (typical) and a dynamic range of 115 dB (typical). The frequency response extends beyond 200 kHz (-3 dB typical).
The LM1971MX/NOPB is controlled via a TTL/CMOS compatible 3-wire serial digital interface. It operates over a voltage range of 4.5V to 12V and is specified for an operating temperature range of -40°C to 85°C.
This component is available in an 8-pin SOIC package suitable for surface mounting. The standard package quantity is 2,500 units on tape and reel.
