TIDA-01504: TI Designs: TIDA-01504 Highly Accurate, Loop-Powered, 4- to 20-mA Field Transmitter With HART Modem Reference Design

Part Number: TIDA-01504
Other Parts Discussed in Thread: ADS1118, TIDA-00483

Hi , We are going to design a hardware for "Loop-Powered, 4- to 20-mA Field Transmitter With HART Modem"  . I was reading the Demo version released by TI named " TI Designs: TIDA-01504 Highly Accurate, Loop-Powered, 4- to 20-mA Field Transmitter With HART Modem Reference Design . I have few question hope someone can give a satisfying answer

1. In the block diagram , as we can see "Sensor+ADC" block is to interface with Demo board externally . I cannot see any connector on the schematic of this Demo. At which point in the Demo board the ADC output can be connected? In the Demo reference manual , I cannot find the explanation of this part like what kind of sensor and ADC can be interfaced and what are requirements?

2.Can you recommend some other Demo board which include SENSOR+ADC+MSP430+HART&DAC +LOOP POWER CIRCUITRY 

3.If there is no such Demo board then can you recommend me some ADC which i can add in hardware design of above Demo ?

Thanks

  • Hi Attif,

    The TIDA-01504 did not include any actual ADC and sensor as they very application specific, where the reference design was only designed to demonstrate the DAC and XTR portion.  The FR5969 is generic enough that you could, in your design, implement any number of ADCs. 

    We do not have a holistic demo that features all of those blocks.  In addition, the TIDA-01504 is not orderable as a demonstration board.

    A good ADC you could consider is the ADS1118, which is low power and commonly found in temperature measurement applications.

    Thanks,

    Paul

  • Ok , thanks for the feedback

  • I just found out another Demo board TIDA-00483 , This seems a better option , it's not exactly according to my requirement but it can be used as a replacement after few modifications in circuitry . Thanks
