1FEATURES DESCRIPTIONThe LM4992 isa stereo audio power amplifier
Availablein Space-Saving WSON Package primarily designed for demanding applications in
• Ultra Low Current Shutdown Mode mobile phones and other portable communication
BTL Output Can Drive Capacitive Loads device applications.Itis capableof delivering1 watt,
per channel,of continuous average powerto an 8Ω
• Improved Click and Pop Circuitry Eliminates BTL load with less than 1% distortion (THD+N) from
Noise During Turn-On and Turn-Off a 5VDC power supply.
TransitionsBoomer audio power amplifiers were designed
• 2.2- 5.5V Operation specificallyto provide high quality output power witha
• No Output Coupling Capacitors, Snubber minimal amount of external components. The
Networksor Bootstrap Capacitors Required LM4992 does not require output coupling capacitors
Unity-Gain Stable or bootstrap capacitors, and thereforeis ideally suited
for mobile phone and other low voltage applications
• External Gain Configuration Capability where minimal power consumption isa primary
requirement.
APPLICATIONSThe LM4992 features independent shutdown control
• Mobile Phones for each channel anda low-power consumption
• PDAs shutdown mode, whichis achieved by driving both
Portable Electronic Devices shutdown pins with logic low. Additionally, the
LM4992 features an internal thermal shutdown
protection mechanism.
KEY SPECIFICATIONS Improved PSRRat 217Hz& 1KHz:64 dB The LM4992 contains advanced click and pop
circuitry which eliminates noise which would
(1KHz)otherwise occur during turn-on and turn-off
• Stereo Output Powerat 5.0V, 1% THD, 8Ω: transitions.
1.07W (typ)The LM4992 is unity-gain stable and can be
• Stereo Output Powerat 3.3V, 1% THD, 8Ω: configuredby external gain-setting resistors.
