To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...
Figure 1. Use the circuit in (a) to measure input bias current on the op amp’s noninverting input. Adding a loop amplifier in (b) keeps the op-amp stable for measurements on the inverting input. The ...
The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...
