Does the LM1117 series have a negative voltage? I have a few questions: 1. Is the 1117 series an LDO? 2. Does the LM1117 series have a negative voltage? I don't know much about LDO. 3. I don't know mu...
Now we need to isolate and sample the 0-25V DC voltage with an accuracy requirement of 1%. Due to the price of the Hall voltage sensor
It’s quite high, I hope to change to other isolation sampling met...
