... Input (J1) Shutdown Control (J2) http://www.cirrus.com Description The CRD35L01 demonstrates the CS35L01 high-effi- ciency Hybrid Class-D audio amplifier. This reference design implements a single-channel amplifier that deliv- ers 1.7 W per full-bridge channel into 8- loads using a single +5-V supply. Differential audio inputs can easily be connected through the J1 header ...

... The CS35L01 requires careful attention to power supply and grounding arrangements to optimize performance and minimize radiated emissions. The decoupling capacitors should be located as close to the CS35L01 as possible. This can be optimized by using both top and bottom side component population as demonstrated by the CRD35L01 boards. 2.1 Power Supply Decoupling Proper power supply decoupling is one key to maximizing the performance of a Class-D amplifier ...
