It is capable of delivering 1.1 watt of • Ultra Low Current Shutdown Mode continuous average power to an 8 Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power • Fast Turn On: 80ms (typ), 110ms (max) with supply. 1.0µF Capacitor Boomer™ audio power amplifiers were designed • BTL Output Can Drive Capacitive Loads up to specifically to provide high quality output power with a 100pF minimal amount of external components. The • Advanced Pop and Click Circuitry Eliminates LM4879 does not require output coupling capacitors Noises During Turn-On and Turn-Off or bootstrap capacitors, and therefore is ideally suited Transitions for lower-power portable applications where minimal space and power consumption are primary • 2.2V - 5.0V Operation requirements. • Available in Space-Saving DSBGA, WSON, and VSSOP Packages The LM4879 features a low-power consumption global shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the APPLICATIONS LM4879 features an internal thermal shutdown • Mobile Phones protection mechanism. • PDAs The LM4879 contains advanced pop and click • Portable electronic devices circuitry which eliminates noises which would otherwise occur during turn-on and turn-off KEY SPECIFICATIONS transitions. • PSRR: 5V, 3V at 217Hz: 62dB (typ) The LM4879 is unity-gain stable and can be configured by external gain-setting resistors. • Power Output at 5V, 1%THD+N: 1.1W (typ) • Power Output at 3V, 1%THD+N: 350mW (typ) • Shutdown Current: 0.1µA (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Boomer is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
