Integrating spread-spectrum technology and an integrated boost converter, the LM48511 Boomer audio amplifier drives an 8-Ω speaker load at 3-W continuous power to enable louder speaker volumes for manufacturers of push-to-talk cell phones, portable GPS and MP3 docking stations, as well as other battery-powered applications. The device lowers EMI emissions more than 11 dB below the FCC limit.
Housed in a 24-pin LLP package, the LM48511 features 80% efficiency, a 3.0 to 5.5-V supply, and THD+N of 1%. ($1.75 ea/1,000—available now.)
