L4733TA
3 Channel 30W Audio Power Amplifier with Mute
LM4733 Channel 30W Audio Power Amplifier with Mute
General DescriptionThe LM4733isa three channel audio amplifier capableof
typically delivering 30W per channelof continuous average
output power intoa 4Ωor 8Ω load with less than 10%
THD+N from 20Hz- 20kHz.
The LM4733 has short circuit protection anda thermal shut
down feature thatis activated when the die temperature
exceeds 150˚C. The LM4733 also hasan under voltage lock
out featurefor click and pop free poweron and off.
Each amplifierof the LM4733 hasan independent smooth
transition fade-in/out mute.
The LM4733 hasa wide operating supply range from ±10V ±32V allowingfor lower cost unregulated power suppliesto used.
The LM4733 amplifiers can easilybe configuredfor bridgeor
parallel operationfor higher power and bi-amp solutions
Key Specifications Output Power/Channelat 10% THD+N,
