Linear - Amplifiers - Audio

BD5423AEFS-E2 amplifiers are audio linear amplifiers designed and manufactured by Rohm Semiconductor. The device is designed to be used in audio devices and other sound-related applications where high-performance amplification and low-noise audio output is needed. The device has a high-voltage rating with a low-voltage control that is ideal for portable devices and other systems where space is limited. It has a wide dynamic range and robust electrical characteristics, making it suitable for many types of audio applications.

Application Field

The BD5423AEFS-E2 audio linear amplifier is ideal for a wide range of audio applications. It is suitable for use in portable handheld devices such as MP3 players, mobile phones and personal digital assistants. It can also be used in other audio systems such as car audio, home theater and audio mixers. The device is also suitable for use in professional audio applications such as professional PA systems, music recording and editing systems, musical instruments, and professional sound systems.

Working Principle

The working principle of the BD5423AEFS-E2 audio linear amplifier is based on the linear amplification of audio signals. The device amplifies the audio signal by increasing its power and reduces distortion and other noises associated with audio signals. The amplifier takes in an analog audio signal and amplifies it through an internal process of linear amplification where the signal is increased in amplitude and power. The amplified output is then fed to an output device such as a speaker, headphones or recording equipment.

The BD5423AEFS-E2 audio linear amplifier has a high power-to-voltage ratio and a low-noise output. It has a dynamic range of up to 55dB, which is greater than what is typically required for audio applications. The device has an output power of 40W RMS and a THD (total harmonic distortion) of 0.04%. It has a wide frequency response from 20 Hz to 20 kHz and an adjustable gain from 0 to 50 dB. The device is also equipped with a temperature sensor to protect against overheating and prolong the life of the device.

Conclusion

The BD5423AEFS-E2 audio linear amplifier is a versatile device that can be used for a wide range of audio applications. It has a high-voltage rating with a low-voltage control that is ideal for portable devices and other systems where space is limited. It has a wide dynamic range and robust electrical characteristics, making it suitable for many types of audio applications. The device is easy to install and use and provides excellent sound quality with low-noise performance.
