LPA2104ASOF Description

Short technical summary and product information.

The LPA2104ASOF is a 3W Class-D mono audio amplifier designed by LOWPOWER for high-quality sound reproduction. Its filterless architecture allows direct speaker drive, reducing system cost and PCB area by eliminating the need for external low-pass output filters. This amplifier features a fixed switching frequency of 550KHz, achieving up to 85% efficiency.

 

Key electrical specifications include an output power of 3W at 10% THD with a 4Ω load and 5V VDD, and 2.3W at 1% THD under the same conditions. It operates with a supply voltage range of 2.5V to 5.5V and boasts a low shutdown current of less than 1uA. The device also includes protection features such as short circuit and thermal shutdown.

 

Packaged in a space-saving SOP-8 surface-mount package, the LPA2104ASOF is suitable for applications requiring compact audio solutions. Its fast startup time of 35ms and minimal external component requirements further enhance its design flexibility.
