LM4096 audio amplifier circuit design

The LM4096 audio amplifier circuit diagram represents a straightforward audio amplifier capable of delivering a maximum output power of 1 watt, utilizing a minimal number of external electronic components. The LM4906, an audio power amplifier, is specifically engineered for demanding applications in mobile phones and other portable devices. It can provide 1W of continuous average power to an 8-ohm BTL load with less than 1% distortion (THD+N) when powered by a +5V supply. The LM4906 features an internal selectable gain of either 6dB or 12dB. Furthermore, it does not require output coupling capacitors or bootstrap capacitors, making it particularly suitable for cell phones and other low-voltage portable applications.

The LM4906 audio amplifier circuit is designed to operate efficiently in compact electronic devices where space and power consumption are critical. The circuit typically includes the LM4906 IC, power supply connections, and input/output terminals. The power supply should provide a stable +5V to ensure optimal performance and minimize distortion.

In typical configurations, the input signal can be fed directly into the amplifier through a resistor-capacitor (RC) coupling network if necessary, although the LM4906's design allows for direct connection in many scenarios. The output stage of the amplifier is configured to drive an 8-ohm speaker load, and the BTL (Bridge-Tied Load) configuration enhances the output power while maintaining low distortion levels.

The selectable gain feature allows designers to adjust the amplification level to suit various applications, providing versatility in design. The absence of output and bootstrap capacitors simplifies the circuit design, reduces component count, and enhances reliability, particularly in portable applications where space is limited.

Overall, the LM4906 audio amplifier circuit is an excellent choice for applications requiring compact, efficient audio amplification with minimal distortion, making it ideal for integration into mobile phones and other portable electronic devices.This LM4096 audio amplifier electronic project circuit diagram is a very simple audio amplifier that will provide a maximum output power of 1 watt, using few external electronic parts.
