Dear TI
Thank you for answer.
I asked about the connection between the single amplifier and the differential amplifier, because the experimental environment I use and the area of the equipment I develop are quite large.
The dsp and insulation solutions provided by ti are very good. But the industrial products I develop are often bulky. Typical examples include welding machines, small electric car chargers, and inverters.
Then the position of sensing voltage and current becomes very long. Often in the laboratory more than 50~cm.
In addition, since the environment is noisy, the sensor circuit itself is often used separately from the controller. If this is not used, high current or high voltage signal must be connected to the controller, which requires very difficult connection depending on the product.
And I use more than 8 channels of signal. In this case, many signal line cables are needed.
There may be a solution such as spi adc, but first, it is difficult to modify it to fit the dsp controller and new code must be developed. And since c2000 implements real time interrupt in ad port, it is preferable to read real time signal rather than controlling adc through spi communication.
Regards,
TI
