op amp controls the IRF520 in the feedback of the load current. In this application, the maximum output current is 1A, and the value of the sense resistor is 0.1Ω. The PCB (printed-circuit board) can also have this small resistance value, which you calculate using the cuprum material’...
Today's high-performance instrumentation amplifiers (in-amps) are not expensive, so it is quite simple to make a bipolar current source using an op amp, an in-amp, and a current-sense resistor, as shown in Figure 10. Such circuits are simpler than the Howland pump, are not dependent on...
Figure 1. A low power, wireless current sense circuit is formed by a low power chopper op amp to amplify the sense voltage. It is digitized using a low power ADC and reference and connected to a SmartMesh IP wireless radio module. A low power, dc-to-dc converter conditions the ...
