MIX3001
2X3W FM Non-Interference Class-D Amplifier
Description
The MIX3001 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 MIX3001 is
capable of driving 3.2W/CH into 3
Ω
at 5V.
The MIX3001 features shutdown and mute
controls functions. High PSRR and differential
architecture provide increased immunity to noise
and RF rectification.
The MIX3001 is available in SOP-16 PB-Free
package.
