FEATURES  
DESCRIPTION  
The LM4890 is an audio power amplifier primarily  
designed for demanding applications in mobile  
phones and other portable communication device  
applications. It is capable of delivering 1 watt of  
continuous average power to an 8BTL load with  
less than 1% distortion (THD+N) from a 5VDC power  
supply.  
2
Available in Space-Saving Packages: DSBGA,  
VSSOP, SOIC, and WSON  
Ultra Low Current Shutdown Mode  
BTL Output Can Drive Capacitive Loads  
Improved Pop & Click Circuitry Eliminates  
Noises During Turn-On and Turn-Off  
Transitions  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. The  
LM4890 does not require output coupling capacitors  
or bootstrap capacitors, and therefore is ideally suited  
for mobile phone and other low voltage applications  
where minimal power consumption is a primary  
requirement.  
2.2 - 5.5V Operation  
No Output Coupling Capacitors, Snubber  
Networks or Bootstrap Capacitors Required  
Thermal Shutdown Protection  
Unity-Gain Stable  
External Gain Configuration Capability  
The LM4890 features a low-power consumption  
shutdown mode, which is achieved by driving the  
shutdown pin with logic low. Additionally, the LM4890  
features an internal thermal shutdown protection  
mechanism.  
APPLICATIONS  
Mobile Phones  
PDAs  
Portable Electronic Devices  
The LM4890 contains advanced pop & click circuitry  
which eliminates noises which would otherwise occur  
during turn-on and turn-off transitions.  
KEY SPECIFICATIONS  
PSRR at 217Hz, VDD = 5V (Fig. 1): 62dB(typ.)  
Power Output at 5.0V & 1% THD: 1W(typ.)  
Power Output at 3.3V & 1% THD: 400mW(typ.)  
Shutdown Current: 0.1μA(typ.)  
The LM4890 is unity-gain stable and can be  
configured by external gain-setting resistors.
