What is the total power consumption of the transducer?

Sign up using Facebook. The flux cancelling current is fed to the output and will be directly proportional to the primary current. The amplifier runs a current through the coil winding so that the flux in the core sums to zero. So the maximum power drawn will consist of two components: And next to that it will draw I s from the supply “in general”. Worst case for the transducer will be with maximum current and voltage drop into minimum RM.

Thank you for clarifications, this is really helpful! Yes, I only care about the power budget since I need to size a power supply. Sign up using Email and Password.

This is represented in the schematic by the X-box. If you measure sine-shaped or small currents, I s will on average be smaller, and so the average power will drop.

It is never driven into saturation if datasheey within spec and never leaves zero so there are no hysteresis effects either. Email Required, but never shown.

The datasheet is not very comprehensive so I am guessing a bit. Post as a guest Name. Home Questions Tags Users Unanswered.

All of these devices work using Hall-effect sensors. In that case you will need to find the rms value of the current you measure to determine the average power you will need for driving I s.

I suspect you only care about your power budget in which case your analysis is correct. Marko Gulin 1 5 The device itself needs 10mA continuously from both supply rails to work. If this is total consumption for both supply pinscan I except la555p the transducer is going to draw equally on each supply pin, i.

You might want to re-phrase the question. The power will be consumed by the transducer and the load RM. This is rather clever as it removes all non-linearities of the core from the performance of the datwsheet.
