1 x 1.7 w cs35l01 放大器參考設計套件

the crd35l01 demonstrates the cs35l01 high-efficiency hybrid class-d audio amplifier. this reference design implements a single-channel amplifier that delivers 1.7 w per full-bridge channel into 8-ohm loads using a single +5-v supply.

differential audio inputs can easily be connected through the j1 header. if desired, the gain can be adjusted through the optional input resistors.

the -sd, -fsd, -hd, or -fhd suffix designates the cs35l01’s operational mode. each of the four boards is configured to operate in each of the four corresponding modes of the cs35l01 device.

device shutdown control is available through the j2 header.
