Vehicle Sound for Pedestrians Amplifier Board (VSP)

Product Use

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

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

The VSP Amplifier Board uses the custom IC (MRXVSP2D).

The VSP Amplifier Board fully satisfies all the requirements of FMVSS#141.

Precision operation is assured by 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 two Digital Control Inputs control the four distinct dB levels of the D Class amplifier gain, as if required by the FMVSS #141.
(GAIN0 and GAIN1)
