1 Watt Fully Differential Audio Power Amplifier With Shutdown Select
LM4898 Watt Fully Differential Audio Power Amplifier With
Shutdown Select
General DescriptionThe LM4898isa fully differential audio power amplifier
primarily designedfor demanding applicationsin mobile
phones and other portable communication device applica-
tions.Itis capableof delivering1 wattof continuous average
powertoan 8Ω BTL load with less than 1% distortion
(THD+N) froma 5VDC power supply.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. The LM4898 doesnot require output
coupling capacitorsor bootstrap capacitors, and thereforeis
ideally suitedfor mobile phone and other low voltage appli-
cations where minimal power consumptionisa primaryre-
quirement.
The LM4898 featuresa low-power consumption shutdown
mode.To facilitate this, Shutdown maybe enabledby either
logic highor low dependingon mode selection. Driving the
shutdown modepin either highor low enablesthe shutdown
selectpintobe drivenina likewise mannerto enable Shut-
down. Additionally, the LM4898 featuresan internal thermal
shutdown protection mechanism.
The LM4898 contains advanced pop& click circuitry which
virtually eliminates noises which would otherwise occur dur-
ing turn-on and turn-off transitions.
Key Specifications Improved PSRRat 217Hz 83dB(typ) Power Outputat 5.0V& 1% THD 1.0W(typ) Power Outputat 3.3V& 1% THD 400mW(typ) Shutdown Current 0.1µA(typ)
Features Fully differential amplification Availablein space-saving packages micro SMD, MSOP,
and LLP Ultra low current shutdown mode Can drive capacitive loadsupto 500pF Improved pop& click circuitry eliminates noises during
turn-on and turn-off transitions 2.4- 5.5V operation No output coupling capacitors, snubber networksor
bootstrap capacitors required Shutdown highor low selectivity
