Differential Analog Sensor Signal

Doug Coutlee 2 years ago • updated 2 years ago • 2

I am looking for a way to use a shunt style current sensor that has a differential analog output with an IQAN module. Does anyone have suggestions? https://riedon.com/resistors/view/ssa  Riedon-Smart-Current-Sensor.pdf

The catalog for the device shows a circuit for converting to a "single ended output", that might be a solution for how to read this via a regular VIN on an IQAN module.

Thank you Gustav. We ended up using a setup with an ADC to convert and amplify the signal before sending it to an IQAN module input as a single ended signal.
