Thanks for sharing, really interested on how you deal with the analog front end for the LTC2400, please post the schematic.
I have few for this 24 bit adc gathering dust for years.

That would be challenging for anyone to use.
After I saw (the late) Jim Williams video on the Linear Technology Voltage reference LTC6655, I bought the 2.5 V version
I will use this thread to post all information I have found about these devices and uses of them
Hello,
one question: do you use the hermetically tight LS8 package or the plastic package?
Mhm, when looking at the video: how can you measure >3V with a 2.5V reference. There is only 12.5% overrange on the LTC2400 device. Or do you use a voltage divider? In this case the pricing of the resistor voltage divider will be much more than the semiconductor parts, if you want to maintain the quality of ADC+reference.
I am not really a 'volt-nut'.
I bought the LTC1050 together with a single 1N829A in order to make an old fashion ref.
Would something like the LM399 work as the voltage reference? How would I get the voltage down, and also, are there any other ADI or TI parts that I can use?

The LTC1050 can only deliver around 2mA. So if you want to supply the 7.5mA constant current for the 1n829A you will need a additional power stage.

Super cool project!
I picked up one of these LTC2400 Arduino breakout boards from Ebay to simplify using it in an arduino project to monitor current into and out of my solar system batteries via a 500amp/50millivolt shunt. Didn't think I had the soldering skills to use it otherwise.... The voltage reference is not as high end as the LTC6655 but it's probably good enough for my project. The board does have pads in place to substitute a somewhat better Analog Devices REF195E 5.0V reference.
This stuff is all new to me but the LTC2400 is just the ticket I needed for my project since the Arduino's built in 10bit ADCs did not have the resolution I needed.
I'm looking forward to seeing what your final build looks like!
NOTE* The CELSIUS is an early Christmas present to some our European Central Continental brothers that like to point of that if it ain't Kelvin, it is not scientific. Nice to see an American datasheet using Celsius.

Got it, but what do you want to expect of a continent that still measures in units of body parts
