The LA42052-E is a linear audio amplifier, specifically designed for use in portable applications. It is a high-performance amplifier with a very small form factor, suitable for applications where size is a constraint. The LA42052-E has excellent power efficiency and a wide input voltage range. It also features a low frequency noise floor and low distortion.

The LA42052-E is designed to amplify signals in the frequency range of 30 Hz to 300 Hz. It has a power output of 10 W RMS and a total harmonic distortion (THD) of 0.3% at an output current of 5 mA. The amplifier also has an input voltage range of 10 V DC to 16 V DC and a working voltage of 12 V DC. The LA42052-E features a unity gain and excellent small signal characteristics such as wide bandwidth and low noise. This makes it suitable for applications such as mobile and portable speakers.

The LA42052-E has a wide variety of applications. It is typically used to drive a loudspeaker in a personal audio and multimedia system. It is also used in portable multimedia players and home theater systems. The amplifier can also be used as a low-power bridged amplifier in general audio and acoustic measurements.

The LA42052-E uses a linear working principle, meaning that the input voltage is increased proportionally to the output voltage. This is achieved by the application of negative feedback across the amplifier, which stabilizes the gain. The gain and input voltage are related by the transfer equation for a unity-gain amplifier.

The LA42052-E has a dual power supply configuration, in which one supply regulates the input signal and the other supplies the output power. This configuration ensures low-level signal distortion and allows the amplifier to operate in stereo, if necessary. The amplifier also has a variable output voltage, which can be adjusted to meet specific requirements.

The LA42052-E is an excellent choice for applications requiring high power output, low distortion, and excellent sound quality. Its linear working principle, wide input voltage range and dual power supply configuration make it suitable for a variety of applications. Its small size makes it an ideal solution for portable applications.
