DESCRIPTION
The LM4941 is a fully differential audio power
amplifier primarily designed for demanding
applications in mobile phones and other portable
communication device applications. It is capable of
delivering 1.25 watts of continuous average power to
a 8Ω load with less than 1% distortion (THD+N) from
a 5VDC power supply. The LM4941 does not require
output coupling capacitors or bootstrap capacitors,
and therefore is ideally suited for mobile phone and
other small form factor applications where minimal
PCB space is a primary requirement.
The LM4941 also features proprietary internal
circuitry that suppresses the coupling of RF signals
into the chip. This is important because certain types
of RF signals (such as GSM) can couple into audio
amplifiers in such a way that part of the signal is
heard through the speaker. The RF suppression circuitry in the LM4941 makes it well-suited for
portable applications in which strong RF signals
generated by an antenna from or a cellular phone or
other portable electronic device may couple audibly
into the amplifier.
Other features include a low-power consumption
shutdown mode, internal thermal shutdown
protection, and advanced pop & click circuitry.
