I would like to measure current but I don't know where to start - how do I choose the right current sense amplifier or current shunt monitor with integrated data converter? What kind of accuracy can I achieve? Please help me to understand!
If you have questions about choosing the right current shunt monitor/current sense amplifier for your application, or how to calculate errors and accuracy, or what to watch out for when you're designing your circuit, then this video series is just what you need!!
