Audio amplifiers are electronic amplifiers that increase the amplitude of an audio signal, thereby creating a louder sound that is more suitable for listening with headphone devices or speaker boxes. The type of amplifier used depends on the stage of the audio signal it processes and its technical requirements. Generally, multiple types of amplifiers are used in audio systems, such as preamplifiers and power amplifiers, where the number and power of these amplifiers varies depending on the size and purpose of the system. In this article, we focus on the 98-1048PBF – an audio amplifier application field and its operating principle.

The 98-1048PBF is an audio power amplifier IC (Integrated Circuit) manufactured by Toshiba. It is a three-stage, direct-coupled PWM (Pulse-Width Modulation) type audio power amplifier with a maximum output of 48W. It has several features that give it excellent performance, such as low distortion, high efficiency, and low noise. This IC requires a single supply voltage of 14V, and can deliver a 7W (1kHz, 10% distortion) output power with only 1.0W of total power dissipation.

The 98-1048PBF can be used in audio systems such as car audio, home theater systems and personal audio devices. Its high efficiency and low noise level, especially at higher frequencies, make it ideal for use in these types of systems. Its low total power dissipaion also allows it to operate in battery-powered systems. In addition, its high output power makes it a great choice for powering large driver loudspeakers.

The 98-1048PBF works on a principle commonly used in PWM amplifiers. This type of amplifier converts the incoming audio signal into a series of digitally pulsed signals to provide a high output power, while still keeping the power dissipation relatively low. To do this, it first converts the incoming audio signal into a PWM control signal. The control signal is then sent to the three output stages of the amplifier, where it is converted back into an analog signal by the amplifier. As a result, the amplifier is able to produce a high-quality, low distortion sound.

The 98-1048PBF is an excellent choice for many audio systems. Its high efficiency and low power consumption make it an ideal amplifier for many applications. Moreover, its high output power makes it ideal for powering large and high-power speakers. Additionally, its low power dissipation and low distortion ratio make it suitable for portable and battery-powered audio devices. With its wide range of features, the 98-1048PBF is a great choice for many audio applications.
