Descriptive summary

Our class-AB car radio audio amplifiers include a wide range of options, so you have a cost-effective way to support a variety of architectures. For platform designs we offer a range of pin-to-pin compatible devices, covering two to four channels and available with best efficiency operation mode. We have affordable solutions for different output power, where a reasonably limited output power (up to 28 W) is required in the head unit. We also offer a range of amplifiers with combined multi-voltage regulators that provide superior sound quality, reduced component count and less assembly effort.
