Hi ,
we want to use MSP430 MCU for one of our project. We need to interface MSP430 with load cell (SEN-14728 or FX29 series).
Do you have any supporting application notes for load cell interface with MSP430?
Do we need to use any intermediate circuits like instrumentation amplifier to interface load cell with MCU? If yes, please recommend those component which is suitable to work with MSP430.
It would be helpful if you could share a suitable block diagram for interfacing the same.
Thanks,
We don't have it. Reffering to this app note, you need a OPA to connect to the load cell. For MSP430, you can connect the ADC input to the OPA output.
