Datasheets and screenshot added.
What do you mean by exclusive connection?
The tests are on a bench and the devices are communicating over a DC line of 24V. (more) |

| Question | — |
Ceramic filter vs ceramic resonator I have a design of a power line communication using the following IC. https://www.yamar.com/datasheet/DS-SIG60.pdf My design is the same as the example circuit in the datasheet of the chip. Schematic The schematic above uses integrated ceramic filters. There are also some suggested part n... (more) |

"Note C3 to provide stability, and R2 to provide some impedance for C3 to work against. "
What does R2 really do here?
Could we use the same topology C3 along with R2 on the other circuit above? (more) |

What I'm calculating is
$$D=\frac{20\text{V}}{-24\text{V}-20\text{V}} = -0.45... $$ (more) |

I did not understand the negative regulator part you're talking about. How would that work? (more) |

I don't mind about wasted power. The device will be inside the lab always. (more) |

You are right. At first I would be happy to have around 0.1% error. I was thinking of using a 12 bit DAC. (more) |

The upper voltage across the load can be a little lower if we calculate the voltage drop across the current sense and the power element. I wouldn't mind even if that voltage drop was around 6V or even 8V. On the other hand the low voltage across the load must be closest to zero possible. (more) |

| Question | — |
DAC controlled high side current source. I'm designing a high side current source that can be controlled with a Digital-to-analog and can source up to 100mA with voltage supply up to 36V. By high side I mean one side of load will be always grounded. Below you can see a reference design of a such circuit. Image alt text In the de... (more) |
