LM4732
Stereo 50W Audio Power Amplifier with Mute
General DescriptionThe LM4732isa stereo audio amplifier capableof typically
delivering 50W per channelof continuous average output
power intoa4Ωor8Ω load with less than 10% THD+N from
20Hz- 20kHz.
The LM4732 has short circuit protection anda thermal shut
down feature thatis activated when the die temperature
exceeds 150˚C. The LM4732 also hasan under voltage lock
out featurefor click and pop free poweron and off.
Each amplifierof the LM4732 hasan independent smooth
transition fade-in/out mute.
The LM4732 hasa wide operating supply range from +/-10V +/-40V allowingfor lower cost unregulated power suppliesbe used.
The LM4732 amplifiers can easilybe configuredfor bridgeor
parallel operationfor 100W mono solutions.
Key Specifications Output Power/Channelat 10% THD+N,
