Part Number: DRV632


Hi Team,

The customer is experiencing below issue and needs your help.

1: The pin has MUTE pin, and the application circuit is EN pin, without MUTE pin, are these two equivalent?

2:Whether the accessory circuit is correct and whether it can realize the audio differential to single-ended function？

Thanks,

    Hi, Annie,

    1.- Could you clarify how the EN pin is being used in this case? This EN pin is not included in the schematic. It is important to notice that the MUTE pin is a low active pin. If this pin is connected to the EN pin, it can be used to enable and disable this device. So, it will be equivalent. The customer would only need to ensure that the MUTE pin reaches the VOL and VOH levels specified in the datasheet.

    2.- Could you provide more details on the accessory circuit, please? It is not included in the schematic neither. 

    Thank you.

    Best regards,
    Luis Fernando Rodríguez S.
