Monolithic Linear IC
For Car Audio Systems
LV47011P
4-Channel BTL Power Amplifier
Overview
The LV47011P is the IC for 4-channel BTL power amplifier that is developed for car audio system.
Pch DMOS in the upper side of the output stage and Nch DMOS in the lower side of the output stage are complimentary.
High power and high quality sound are realized by that.
This IC incorporate various functions (standby switch, muting function, and various protection circuit) necessary for car
audio system. Also, it has a self-diagnosis function.

• Built-in muting function (pin 22)
• Built-in Standby switch (pin 4)
• Built-in Self-diagnosis function (pin 25) :
Signal output in case of output offset detection, shorting to V , shorting to ground, and load shorting.
CC
• Electric mirror noise decrease
• Built-in various protection circuit (shorting to ground, shorting to V , load shorting, over voltage and thermal shut

down)
• No external anti-oscillation part necessary.
Note 1 : Please do not mistake connection.
A wrong connection may produce destruction, deterioration and damage for the IC or equipment.
Note 2 : The protective circuit function is provided to temporarily avoid abnormal state such as incorrect output connection.
But, there is no guarantee that the IC is not destroyed by the accident.
The protective function do not operate of the operation guarantee range. If the outputs are connected incorrectly, IC
destruction may occur when used outside of the operation guarantee range.
Note 3 : External parts, such as the anti-oscillation part, may become necessary depending on the set condition. Check their
necessity for each set.
