MAX97003音频子系统集成了单声道扬声器放大器和立体声耳机放大器。耳机和扬声器放大器具有独立的音量和开/关控制。其四个输入可配置为两个差分或四个单端输入。为了大限度地减少输出噪声,无论是耳机和扬声器输出都采用向下扩展器/噪声门,在没有所需的输入信号时,衰减噪声。扬声器的输出采用可调的动态范 The MAX97003 audio subsystem integrates a mono speaker amplifier and a stereo headphone amplifier. Headphones and speaker amps have separate volume and on / off controls. The four inputs can be configured as two differential or four single-ended inputs. To minimize the output noise, the down expander / noise gate is used for both the headphone and speaker outputs to attenuate noise in the absence of the desired input signal. The speaker’s output uses an adjustable dynamic range
