BL63162X3W Ultra low EMI Class-D Amplifier
Description
The BL6316 is a high efficiency, 3W/channel
stereo class-D audio power amplifier. A Low noise,
filterless architecture eliminates the out filter, it
required few external components for operation to
save the board space and cost.
Operating from a single 5V supply, the BL6316 is
capable of driving 3.2W/CH into 3 at 5V.
The BL6316 features shutdown and mute controls
functions. High PSRR and differential architecture
provide increased immunity to noise and RF
rectification.
The BL6316 is available in SOP-16 PB-Free
package.
