Frequently Asked Questions
What output power and efficiency does the PAM8304ASR deliver at a 5V supply?
At a 5V supply, the PAM8304ASR delivers up to 3W of output power into an 8-ohm load with up to 90% efficiency. The Class D switching architecture minimizes power dissipation as heat, making it highly suitable for battery-operated portable speakers and tablets where thermal management is critical.
What supply voltage range does the PAM8304ASR support, and how does this benefit portable designs?
The PAM8304ASR operates from a supply voltage range of 2.5V to 5.5V, covering single-cell Li-ion (3.7V nominal) and standard 5V USB rails. This flexibility allows designers to power the amplifier directly from a battery without a boost converter, reducing BOM cost and PCB area in compact audio products.
How does the MSOP-8 package footprint of the PAM8304ASR compare to typical DIP audio amplifiers?
The MSOP-8 package measures approximately 3.0 mm x 3.0 mm with 0.65 mm pitch, far smaller than 8-pin DIP packages at 9.1 mm x 6.4 mm. This size reduction is essential for slim tablet and TWS earphone PCBs where space is limited, while still delivering 3W of Class D audio output at 18 dB gain.
