SNAS272B –OCTOBER 2004–REVISED APRIL 2013  
LM4924 Boomer™ Audio Power Amplifier Series 2 Cell Battery, 40mW Per Channel  
Output Capacitor-Less (OCL) Stereo Headphone Audio Amplifier  
Check for Samples: LM4924

FEATURES  
DESCRIPTION  
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.

OCL Mode for Stereo Headphone Operation  
Unity-Gain Stable  
•
•
•
“Click and Pop” Suppression Circuitry for  
Shutdown On and Off Transients  
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.  
•
•
Active Low Micropower Shutdown  
Thermal Shutdown Protection Circuitry  
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.
