LM1972 | 具有静音功能的 μPot 2 通道 78dB 音频衰减器 The LM1972 is a digitally controlled 2-channel 78dB audio attenuator fabricated on a CMOS process. Each channel has attenuation steps of 0.5dB from 0dB–47.5dB, 1.0dB steps from 48dB–78dB, with a mute function attenuating 104dB. Its logarithmic attenuation curve can be customized through software to • 3-Wire Serial Interface\n• 104dB Mute Attenuation\n• Total Harmonic Distortion + Noise: 0.003 % (max)\n• Attenuation range (excluding mute): 78 dB (typ)\n• Signal-to-noise ratio (ref. 4 Vrms): 110 dB (min)\n• Channel separation: 100 dB (min); | TI 德州仪器 | ||
