Amplifier With Shutdown
Checkfor Samples: LM4927
1FEATURES DESCRIPTION
The LM4927 isa fully differential audio power
23• Fully Differential Amplification amplifier primarily designed for demanding• Availablein Space-Saving Micro-Array WSON applications in mobile phones and other portablePackage communication device applications.Itis capableof Ultra Low Current Shutdown Mode delivering 2.5 wattsof continuous average powertoa load with less than 10% distortion (THD+N) from• Can Drive Capacitive Loads upto 100pF a 5VDC power supply.• Improved Pop& Click Circuitry Eliminates
Boomer audio power amplifiers were designedNoises During Turn-On and Turn-Off specificallyto provide high quality output power withaTransitions minimal amount of external components. The• 2.4- 5.5V Operation LM4927 does not require output coupling capacitors No Output Coupling Capacitors, Snubber or bootstrap capacitors, and thereforeis ideally suited
Networksor Bootstrap Capacitors Required for mobile phone and other low voltage applications
where minimal power consumption isa primary
requirement.APPLICATIONS
The LM4927 featuresa low-power consumption• Mobile Phones
shutdown mode. To facilitate this, Shutdown may be• PDAs enabled by logic low. Additionally, the LM4927• Portable Electronic Devices features an internal thermal shutdown protection
mechanism.KEY SPECIFICATIONS The LM4927 contains advanced pop& click circuitry• Improved PSRRat 217Hz, 85dB (Typ) which eliminates noises which would otherwise occur
during turn-on and turn-off transitions.• Power Outputat 5.0V@ 10% THD (4Ω), 2.5W
(Typ) Power Outputat 3.3V@ 1% THD, 550mW (Typ) Shutdown Current, 0.1µA (Typ)
