LM4666 General Description

The LM4666 is a fully integrated single-supply high efficiency switching audio amplifier.It features an innovative modulator that elimina testhe LC output filter used with typical switching amplifiers.Eliminating the output filter reduces parts count, simplifies circuit design,and reduces board area.The LM4666 processes analog inputs with a delta-sigma modulation technique that lowers output noise andT HD when compared to conventional pulse width modulators.

The LM4666 is designed to meet the demands of mobile phones and other portable communication devices.Operating on as ingle 3V supply,it is capable of driving 8Ω transducer loads at a continuous average output of 450mW with less than 1%THD+N.Itflexible power supply requirements allow operation from 2.8V to 5.5V.

The LM4666 has high efficiency with an 8Ω transducer load compared to a typical ClassAB amplifier.With a 3V supply, the IC'sefficiency for a 100mW power level is79%,reaching84% at 450mW output power.

The LM4666 features a low-power consumption shutdown mode.Shutdown may be enabled by driving the Shutdown pin to a logic low (GND).

The LM4666 has fixed selectable gain of either 6dB or 12dB.The LM4666 has short circuit protection against a short from the outputs to VDD or GND.
