Hello Bob,
Thank you for replying to my earlier query regarding ADS122U04 interfacing with RTD PT100.
In the same project I also need to use ADS122U04 for measuring Engine Oil pressure (in heavy vehicles) -
using MEAS make M5100 series pressure transducer (either having 4 to 20mA output OR 0-5Vdc output - yet to be decided).
I am unable to find an application note to help me in designing the interfacing circuit between such a pressure transducer and ADS122U04.
I also need your suggestion on which type of pressure transducer should I use i.e. the one having 4 to 20mA output OR 0-5Vdc output ?
The other details are as follows:-
a) I shall be using the WQFN (3mmx3mm) package of ADS122U04.
b) ADS122U04 and associated circuitry will be populated on a very small PCB (15mmx20mm) that shall be fitted in a very small enclosure that will be fitted on the pressure transducer.
c) This above mentioned module shall transmit the 24Bit results of AtoD conversions over long distance (for processing purpose) using UART interface of ADS122U04.
Thank you,
Regards,
Milind Risbud.
