Audio power amplifier circuit using MAX9789A and MAX9713 chips
Source: InternetPublisher:桂花蒸 Keywords: Audio power amplifier power amplifier circuit mono Updated: 2021/12/24
Shown is the audio power amplifier circuit using the MAX9789A and MAX9713 chips in a typical notebook computer. The audio signal from the sound
card chip is sent to the audio power amplifier MAX9789A through the coupling capacitor . After amplification, it outputs
the left and right channel signals used to drive the speaker. The mono audio signal output by the vocoder is sent to the IN terminal of the MAX9713, and is amplified to drive the mono speaker.
