The LM4924 is a Output Capacitor-Less (OCL) stereo headphone amplifier, which when connected to a 3.0V supply, delivers 40mW per channel to a 16Ω load with less than 1% THD+N.

With the LM4924 packaged in the VSSOP and SON packages, the customer benefits include low profile and small size. These packages minimizes PCB area and maximizes output power.

The LM4924 features circuitry that reduces output transients (“clicks” and “pops”) during device turn-on and turn-off, and Mute On and Off. An externally controlled, low-power consumption, active-low shutdown mode is also included in the LM4924. Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount packages.
