The DAC output of the MCU is passed through the DAC0832

QWE4562009

The DAC output of the MCU is passed through the DAC0832 [Copy link]

Wouldn't it be better to use the MCU to generate DAC directly through DAC0832

? What are the considerations for using DAC chip DAC0832? (Generate two sets of waveforms with positive and negative inversion?)

It can also be done directly using the two PWM ports of the MCU! DAC0832 is also quite expensive

Compare the parameters of DAC0832 with those of the microcontroller DAC and you will know the difference.

It is not as accurate as DAC output. In addition, the output of single-chip microcomputer requires a lot of programming, while DAC seems to be able to output as long as the value is given. It is relatively simple

This actually depends on the actual needs of the product. Dedicated DAC works more reliably and stably, with pure hardware settings and no need to write programs.
