LM4924MM-LM4924SD
2 Cell Battery, 40mW Per Channel Output Capacitor-Less (OCL) Stereo Headphone Audio Amplifier
LM4924 Cell Battery, 40mW Per Channel Output Capacitor-Less
(OCL) Stereo Headphone Audio Amplifier
General DescriptionThe LM4924isa Output Capacitor-Less (OCL) stereo head-
phone amplifier, which when connectedtoa 3.0V supply,
delivers 40mW per channeltoa 16Ω load with less than 1%
THD+N.
Withthe LM4924 packagedinthe MM andSD 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
MuteOn and Off.An externally controlled, low-power con-
sumption, active-low shutdown modeis also includedin the
LM4924. Boomer audio power amplifiers are designed spe-
cificallyto use few external components and provide high
quality output powerina surface mount packages.
Key Specifications OCL output power (RL =16Ω,VDD= 3.0V, THD+N= 1%) 40mW (typ) Micropower shutdown current 0.1µA (typ) Supply voltage operating range 1.5V< VDD< 3.6V PSRR 100Hz, VDD= 3.0V,AV=2.5 66dB (typ)
Features 2-cell 1.5Vto 3.6V battery operation OCL modefor stereo headphone operation Unity-gain stable “Click and pop” suppression circuitryfor shutdownOn
andOff transients Active low micropower shutdown Thermal shutdown protection circuitry
