1FEATURES DESCRIPTION

The LM4666isa fully integrated single-supply high No Output Filter Required for Inductive efficiency switching audio amplifier.It features anTransducers innovative modulator that eliminates the LC output• Selectable Gainof 6dBor 12dB filter used with typical switching amplifiers. Very Fast Turn On Time: 6ms (typ) Eliminating the output filter reduces parts count,
simplifies circuit design, and reduces board area. The• Minimum External Components LM4666 processes analog inputs witha delta-sigma• "Click and Pop" Suppression Circuitry modulation technique that lowers output noise and Micro-Power Shutdown Mode THD when compared to conventional pulse width
modulators.• Short Circuit Protection Availablein Space-Saving NHK0014A Package The LM4666is designedto meet the demandsof
mobile phones and other portable communication
devices. Operating ona single 3V supply,it isAPPLICATIONS capable of driving 8Ω transducer loads at a• Mobile Phones continuous average outputof 450mW with less than PDAs 1%THD+N. Its flexible power supply requirements
allow operation from 2.8Vto 5.5V.• Portable Electronic Devices
The LM4666 has high efficiency with an 8ΩKEY SPECIFICATIONS transducer load compared toa typical Class AB
amplifier. Witha 3V supply, the IC's efficiency fora• Efficiencyat 3V, 100mW into 8Ω Transducer: 100mW power levelis 79%, reaching 84%at 450mW79% (typ) output power.• Efficiencyat 3V, 450mW into 8Ω Transducer: The LM4666 featuresa low-power consumption84% (typ) shutdown mode. Shutdown may be enabled by• Efficiencyat 5V, 1W into 8Ω Transducer: 85% driving the Shutdown pintoa logic low (GND).(typ) The LM4666 has fixed selectable gainof either 6dB• Total Quiescent Power Supply Current: 7.0mA or 12dB. The LM4666 has short circuit protection(typ) againsta short from the outputsto VDDor GND. Supply Current: 0.02µA 2.8V 5.5V
