1FEATURES DESCRIPTION

The LM4674 isa single supply, high efficiency, Output Short Circuit Protection 2.5W/channel, filterless switching audio amplifier.A• Stereo ClassD Operation low noise PWM architecture eliminates the output No Output Filter Required filter, reducing external component count, board area
consumption, system cost, and simplifying design.• Logic Selectable Gain Independent Shutdown Control The LM4674is designedto meet the demandsof
mobile phones and other portable communication• Minimum External Components devices. Operating froma single 5V supply, the• Click and Pop Suppression device is capable of delivering 2.5W/channel of Micro-Power Shutdown continuous output powertoa 4Ω load with less than
10% THD+N. Flexible power supply requirements• Availablein Space-Saving 2mmx 2mmx allow operation from 2.4Vto 5.5V.0.6mm DSBGA, and 4mmx 4mmx 0.8mm
WQFN Packages
The LM4674 features high efficiency comparedto
conventional Class AB amplifiers. When driving anAPPLICATIONS 8Ω speaker froma 3.6V supply, the device features
85% efficiencyat PO= 500mW. Four gain options are• Mobile Phones pin selectable through the G0 and G1 pins.• PDAs Output short circuit protection prevents the device• Laptops from being damaged during fault conditions. Superior
click and pop suppression eliminates audibleKEY SPECIFICATIONS transients on power-up/down and during shutdown.
Independent left/right shutdown control maximizes• Efficiencyat 3.6V, 100mW into 8Ω: 80% (typ) power savingsin mixed mono/stereo applications.• Efficiencyat 3.6V, 500mW into 8Ω: 85% (typ) Efficiencyat 5V, 1W into 8Ω: 85% (typ) Quiescent Power Supply Current 3.6V supply: 4mA Power Outputat VDD= 5V, 2.5W (typ) 0.03μA
