LV49157V

Class-D Audio Power Amplifier with built-in Headphone Amplifier BTL 15W × 2ch

ON Semiconductor 

Operation Mode Summary

LV49157V

STBY mode (STBY = L, MUTE = L and HP_STBY = L)

Each bias becomes off state when the regulator in IC has been turned off.

The most of circuits becomes off state.

The supply current : 1μA (typical).

MUTE mode (STBY = H and MUTE = L)

Each bias becomes on state when the regulator in IC has been turned on.

When more than half of the circuits are active, the amplifier in the output stages become off.

The supply current : 20mA (typical).

Operation mode (STBY = H, MUTE = H and HP_STBY = H)

The LV49157V operates as D-class amplifier and Headphone amplifier.

The output signal is synchronized with the input signal.

The current of the main amplifier is 45mA (typical) in our recommendation condition, and the current of the headphone

amplifier is 8mA (typical) at RG=0.
