TINA/Spice/AMC1200-Q1: AMC1200 shunt connexion

Part Number: AMC1200-Q1
Other Parts Discussed in Thread: TINA-TI, AMC1200

Tool/software: TINA-TI or Spice Models

Hello,

I'm currently designing current sense measuring in H bridge and I have a question about GND1 connexion: in typical application, shunt resistor is connected to GND1 but there is no explanation about this. I made SPICE simulation and its working fine. It is mandatory to connect shunt resistor to GND1 ?

Regards

  • Hi Jeremy,

    In the AMC1200 datasheet, the shunt is shown connected to GND1 which is the typical application - this has to do with maintaining the common mode voltage level on the input side of the AMC1200. The shunt could also be connected to a small offset voltage, so long as the inputs remained within the common mode range of the device.
