STPA008-QIX

Linear - Amplifiers - Audio

STPA008-QIX is a multifunction power amplifier manufactured by STMicroelectronics. It is primarily used in automotive audio systems, home theater systems and public address systems. The amplifier is built using a high-performance Class B driver stage and a high-efficiency Class D receiver stage. This allows it to deliver high power to the load with minimal power dissipation. It also has a low distortion and low noise structure, making it ideal for audio applications.

The STPA008-QIX power amplifier is capable of delivering up to 25W of RMS power at 4Ω load. It can be used with a wide range of inputs, including reel-to-reel tape, mp3 players, CD players and other sources. The amplifier is designed to provide a high quality audio reproduction with a low distortion level and a wide dynamic range. It also incorporates a thermal cut-off device for protection against over-temperature and short-circuit conditions.

In order to operat?the amplifier, a power supply between 10V and 50V is required. This power goes through a power MOSFET stage, which biases the driver transistors. It also provides a load current capacity of up to 6 A. The output voltage swing is determined by the power supply voltage and by a gain setting input. This gain setting input is adjustable from 0 to 40 dB. This allows users to adjust the amplifier to suit their application.

The working principle of STPA008-QIX is based on Class B and D power amplifier stages. The Class B driver stage provides a high power output with low power dissipation. The Class D receiver stage is then used to amplify the audio signal and convert it into electrical energy. The output signals from the Class D stage are then fed to the load. This combination of Class B and D stages enables the amplifier to provide a high power output while keeping power dissipation low.

The STPA008-QIX provides an ideal solution for applications requiring high power and low distortion. The high efficiency and low distortion make it ideal for automotive audio systems, home theater systems and public address systems. The amplifier is also relatively easy to configure and use, making it suitable for a wide range of applications. The combination of high quality audio reproduction and low power dissipation makes the STPA008-QIX an excellent choice for any audio system.
