www.ti.com SNAS347C – JUNE 2006 – REVISED MAY 2013 LM4941 1.25 Watt Fully Differential Audio Power Amplifier
With RF Suppression and Shutdown
Check for Samples: LM4941, LM4941SDBD, LM4941TMBD FEATURES 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. 1 2 Improved RF Suppression, By Up to 20dB
Over Previous Designs in Selected
Applications
Fully Differential Amplification
Available in Space-Saving DSBGA Package
