Hi Team,

Can you please help review the TLV320AIC3212 schematic as attached?

And does the AIC3212 can output the square wave as below picture for buzzer?

Thanks.

    Hi, Prescott,

    The schematic seems to be in order. I only recommend to connect the unused analog inputs (IN1R & IN4L) to a 0.47uF capacitor to ground.

    Regarding your question about the square wave, the buzzer is connected to a Class-D differential output. It generates square wave pulses for its behavior. The wave voltage is determined by the SPLVDD and SPRVDD power supplies. So, the square wave can be generated.
