LA47510
Monolithic Linear IC
BTL (50W×4) Power IC for
Car Stereo Systems
Overview
The LA47510 is a BTL 4-channel (50W×4) power IC for car stereo. The output stage uses a pure complementary
format with a V-PNP transistor on the upper side and a NPN transistor on the lower side, making it possible to obtain
high power output and excellent sound quality.
This IC incorporates various functions (standby switch, mute function, full complement of protection circuits) needed
for car audio, and also has a self-check (output offset detection) function.
Functions & Features
• 50W×4 maximum output (at VCC=14.4V, RL=4Ω)
• Very low external component count
• Onchip offset detector
• Onchip offset detector shutoff switch
• Mute function
• Standby switch
• Full compliment of protection circuits (including shorting to the power supply, shorting to ground, load short-circuit,
overvoltage, thermal protection)

Caution 1: Never make wrong connection. A wrong connection would cause fatal damage or performance degradation to the IC or
equipment.
Caution 2: The protective circuit functions are provided to temporarily avoid abnormal states such as incorrect output connections,
and do not guarantee that IC destruction will not occur.
These protective functions do not operate outside of the operation guarantee range. If the outputs are connected
incorrectly, IC destruction may occur when used outside of the operation guarantee range.
