TIDM-02005: Analog Front End

Part Number: TIDM-02005
Other Parts Discussed in Thread: EVM430-FR6043, TS5A9411

Tool/software:

this says for water metering need to remove all jumpers on J9. then its hard to understand that how MCU communicate with the tranducers. Because it seems MCU and Transducers are connected via that J9 headers.

Hi Sudeepa, for this you would connect the transducer directly to the right side pins of header J9. Hope this helps!

That mean we can connect tranducers directly to the mcu(with resistor). no need of below part for water metering?

Hi Sudeepa, the connections based on this particular design will be on the left side actually, and will connect to the MCU via the capacitor/resistor circuitry. When using the EVM430-FR6043 in the water metering configuration, the TS5A9411 is bypassed and not used as is the OPA, so you do not need this for the TIDM-02005 implementation. If it is a gas metering application, this is when you would use the AFE portion of the design.
