Class D amplifiers generally use a low-pass filter to attenuate the switching noise in the output waveform while passing the audio signal to the loudspeaker, but many engineers are not familiar with ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

Resulting from a proprietary output modulation design, the LX1701 Class-D audio amplifier specifies a quiescent-current consumption of 2 mA and is capable of filter-less operation in many applications ...

Reducing parts count, the LM4667 fixed-gain, Class D audio amplifier requires no output filter and comes in a nine-bump, micro SMD package. A unique modulator is said to be responsible for eliminating ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...
