Description
The PAL007C is Class AB Car Audio Amplifier.
An AB class audio power amplifier is a type of amplifier that combines the characteristics of Class A and Class B amplifiers. It is designed to provide improved efficiency compared to Class A amplifiers while maintaining good audio quality and reduced distortion compared to Class B amplifiers.
In an AB class amplifier, the input audio signal is split into two parts: a positive half-cycle and a negative half-cycle. Each half-cycle is amplified by a separate set of transistors (one for the positive half and another for the negative half) working in a push-pull configuration.
When it comes to power audio MOSFETs, there are several models that are commonly used in high-power audio amplifier applications. These MOSFETs are specifically designed to handle the demands of audio amplification, providing high power output with low distortion.
Here are a few examples of power audio MOSFETs:
IRFP240 and IRFP9240: These are popular complementary MOSFET pairs commonly used in high-power audio amplifier designs. The IRFP240 is an N-channel MOSFET, while the IRFP9240 is a P-channel MOSFET. They can handle high voltage and current levels and are known for their excellent audio performance.
IRFB4227 and IRFB4228: These MOSFETs from Infineon Technologies are designed for high-performance audio amplifiers. They offer high power handling, low on-resistance, and excellent linearity.
