Product Use

This Vehicle Sound for Pedestrians Amplifier IC (VSP) is especially developed for Automotive use.

The class-D Stereo Amplifier IC requires 10 VDC to 30 VDC power.

The VSP Amplifier IC (MRXVSP2D) is supplied in DIP-20 package.

Precision operation is assured by built in IC oscillator.

Vcc Power Input Pin is connected to nominal +12 VDC that has a Common Ground with the IC sound Input and Output as well as Control lines.

The 2 Digital Control Inputs control the four levels of the D Class amplifier gain.
