Hai Collin Wells.
In continution to the above discussion, IN TIPD164 the cjc is range is 0 to 50C. So to reduce the non linearity they have placed 2.2Kohm resistance (that is equall to resistance of thermistor at 25C) parrellel to thermistor.
My CJC…
Mukesh,
The RCV420 is a legacy device introduced to the market about 36 years ago, and therefore, there is no evaluation board for this particular device. Currently, there is no an exact equivalent integrated device into a single IC for a 4-20mA input…
Hi Jose,
I would suggest taking a look at TIPD164 which is a design geared to the ADS1248, but it uses pretty much all the inputs you desire. You could take portions of this schematic and determine how best to connect them to the 4 input channels of…
Hi Nandha,
Thanks for sharing further inputs.
I see that the MCU is on the left side of isolator sitting on system ground labelled C_GND. The outputs of digital isolator and RS-485 are all on the isolated ground labelled ISO_GND on the isolated…
Harish,
I assume that you mean "thermocouple" and not "thermonuclear".
I wouldn't use the PCM1808 for this application. It's generally an audio adc and used for more ac applications. For the ADS7813, you could use it and it would probably work…
