Hi Tao,
We don't characterize the minimum quiescent current for the REF5045-Q1. Below is a graph from the datasheet that shows the typical quiescent current for the part under different temperature and input voltage condition without a load.

Ming,
I did get the latest schematic from James, and I'll post the responses here.
1. I mentioned this before, but there are multiple ground designators. I would make sure that this is cleaned up to make sure that the layout is done smoothly and…
Part Number: ADS131A04 Other Parts Discussed in Thread: INA827 , TM4C1294NCPDT
Dear all,
I'm using the ADS131A04, 4-channel delta-sigma ADC, in a strain gauge amplifier design. For my application, 12 channels are required in total but board area…
Hello Michael,
The issue with one reference for many converters is reference stability and noise.
Reference pins are dynamic inputs that send kickback currents back to the reference and the reference has to correct the voltage very quickly. The…
Hi Sravya,
Attached is the C2000 PCB design guide PDF and very good to review even if you are an avid PCB designer.

Part Number: REF5050A-Q1 Other Parts Discussed in Thread: REF34-Q1 Tool/software: REF5050A-Q1 is rated for -40 to 125 deg. C, not sure if this device will function at -55 deg C ambient temperature or not?
Or do you have minimum -55 deg. C to 125 deg…
Part Number: ADS8881 Other Parts Discussed in Thread: ADS8883 the ADS8881 has different modes. i wanted to use the "10.4.2.1 Daisy-Chain Mode Without a Busy Indicator" because it seems to be the easiest if You only want to connect one device per SPi-interface…
If your truly interested why 1/2 LSB settling even though it seems an MSB issue, PDF below link is an excellent 2018 source.

Hi Cedric,
Nope no firmware is required to establish the connection with emulator. You can once go through: F28335 controlCARD ZJZ Schematic [R2.2].pdf
Also, here are hardware guidelines:
