S1A0071 Audio Processor for Class-D Power AMP

Digital & Analog Co., Ltd. (Rev. 1.0) -3-

1. INTRODUCTION

The S1A0071 is an Audio processor for Class D-type audio amplifier, will help you to make more

easier the class D type audio amplifier and sound system. This is designed by the Cool Power

Processing (CPP

) technology. The CPP have a characteristic of high fidelity and high power

efficiency.
