The following is the circuit diagram of the [LM4818 single-chip bridge power amplifier IC pin circuit].

The LM4818 monolithic bridge audio power amplifier operates from a 5V supply and can deliver 350mW RMS power to drive a 16Ω load, or output 300mW RMS power to drive an 8Ω load with 10% total harmonic distortion and noise (THD+N). This device is ideal for compact audio applications due to its surface-mount design, which helps save PCB space. It also requires the fewest external components among similar ICs, ensuring high-quality audio output with minimal complexity.

Designed for versatility, the LM4818 is available in a SOP surface-mount package, making it suitable for a wide range of applications. Its pinout configuration is clearly shown in the accompanying diagram, allowing engineers to easily integrate it into their designs. Whether you're working on portable audio devices, small speakers, or embedded systems, the LM4818 offers reliable performance and efficiency.
