Audio special purpose technology, especially STA369BWTR, has had a major influence on the audio industry. By understanding the application field and working principle of this technology, one can gain a better understanding of the potential of audio engineering.

Application Field

The STA369BWTR is a stereo audio amplifier of comparable precision and power which is designed for various applications such as portable audio systems and automotive audio systems, due to its highly efficient operating mode. The amplifier also supports up to seventy watts of continuous output power from a single supply and is capable of safe operation with short circuit and thermal protection features. In terms of performance, the STA369BWTR is highly capable of providing efficient, reliable and accurate sound reproduction.

Furthermore, its ‘bi-stable’ power control scheme allows the amplifier to be switched rapidly between on and off, thereby reducing power consumption and extending battery life. Additionally, the device also features variable pre-gain control, automatic level control (ALC), and improved high-order harmonic suppression when used with passive components.

Due to its wide range of features and applications, the STA369BWTR is the ideal choice for a range of audio special purpose applications. Its versatile design allows it to be used not only in loudspeaker and headphone applications, but also in automotive sound card implementations.

Working Principle

The operating principle of the STA369BWTR amplifier is based on the MOSFET type of amplification. This type of amplification utilizes transistors to create an amplified voltage source from an external source. The MOSFETs provide high level of efficiency, as well as a robust and reliable operation, that makes them ideal for modern audio applications.

The STA369BWTR requires values of supply current, supply voltage, and bias current to effectively operate. The amplifier consists of two independent N-channel MOSFETs and operates with a class AB amplifying configuration. The device also features a built-in output stage protection in the form of short-circuit protection, over- temperature protection, and reverse current protection.

In addition, the amplifier also includes a unique bi-stable power control scheme that enables the device to switch quickly back and forth between on and off states in order to reduce power consumption. The bi-stable power control scheme also allows for an improved performance and for smoother transition between different operating states.

The STA369BWTR amplifier is designed to provide an extremely efficient and reliable performance in any audio application. It offers excellent versatility in both amplifier performance and its inclusion of both bi-stable power control to reduce power consumption and improved harmonic suppression when used with passive components.
