This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

Combining two TLx431 regulators together to make a programmable gain current mirror that can be also used for a current loop ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Popularity and perceived advantages of current-mode control (CMC) have made it de rigueur as a loop control architecture with many power management IC manufacturers and power supply vendors. Also ...

Instrument loop problems are frustrating at the best of times and can be really time consuming affairs to deal with. Most of the time these problems are related to isolation and ground faults.
