LM4992 bassed Stereo audio power amplifier circuit and explanation

Using the LM4992 stereo audio power amplifier you can design a very simple audio power amplifier electronic project , that can be used for portable electronic devices .

This power audio amplifier circuit is capable of delivering 1 watt, per channel, of continuous average power to an 8ohmsBTL load with less than 1% distortion (THD+N) from a 5VDC power supply.
This audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.

The LM4992 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

Some of the main features of the LM4992 audio amplifier designed for portable electronic devices are : independent shutdown control for each channel and a low-power consumption shutdown mode, internal thermal shutdown protection mechanism , advanced pop & click circuitry , unity-gain stable and can be configured by external gain-setting resistors.
This audio amplifier circuit can be powered from a wide range input voltage between :2.2 volts and 5.5 volts .
