On page 19 there is recommended schematic for class D output stage.
If you search for DSP with analogue outputs - take a look at ADAU1701.

DSPOWER-2040-CRV4C
Can it be controlled with 485 PC?
Can I input and output analog signals?
How much is it?
Can you buy it in China?
Thank you

There is no serial communication. It is for stand alone application.
Yes, you can input analog ou digital audio (s/pdif). This module output analog audio and PWM modulation.
I paid U$ 48.00.
Can you buy it in Brazil only. (not chinese product)
This is dirtier than Chinese. The gain of an open-loop PWM amplifier changes with supply voltage sag. The transition from discontinuous inductor current (DCM) to continuous inductor current (CCM) is a source of low volume distortion. The whole idea of tri-level open-loop PWM amplification is aimed to 10% THD.
edit: And yet, it is way to go for AC power inverters.

No RS485 is not good debugging

what to debug, software?
You not need write software for this module.
Eve said: "The gain of an open-loop PWM amplifier changes with supply voltage sag." Yes, the power is proportional to the supply voltage.
I use estabilized power supply.
