LM4924
2 Cell Battery, 40mW Per Channel Output Capacitor-Less
(OCL) Stereo Headphone Audio Amplifier
General Description
The LM4924 is a Output Capacitor-Less (OCL) stereo head-
phone amplifier, which when connected to a 3.0V supply,
delivers 40mW per channel to a 16
load with less than 1%
THD+N.
With the LM4924 packaged in the MM and SD 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 con-
sumption, active-low shutdown mode is also included in the
LM4924. Boomer audio power amplifiers are designed spe-
cifically to use few external components and provide high
quality output power in a surface mount packages.
