Description
These monaural Class D speaker amps have ALC function, and are compatible with differential analog input, making them optimized for a wide variety of applications, from portable devices such as mobile phones and laptop computers to home appliances and healthcare equipment with built-in speech synthesis. In addition, an efficiency of 90% contributes to lower heat generation and greater energy conservation.
