Hello Robert,
When using bipolar supplies, connect REFN to AVSS, or -2.5V. The reference circuit should also be referred to AVSS. In this case, you can use either 2.5V or 4.096V reference values.
The evaluation board uses the REF6225, which works well…

Part Number: ADS127L11 Other Parts Discussed in Thread: REF6225 , Tool/software: Dear Experts,
The design circuit diagram is as follows. During debugging, we found that the sampled voltage value will experience a jump, which is the actual voltage value…
Part Number: REF6225 I have a customer who is asking questions on how the thermal specifications apply to this part.
The web page and the data sheet seem to indicate that the part is designed to operate from -40C to 125C.
The device comparison table …
Part Number: REF6225 Other Parts Discussed in Thread: REF6025 Hello,
At this time, I'am work with a REF6225 voltage reference. Through the analysis of the data sheet, I'am saw that it would be necessary to use a capacitor with a series resistor at the…
Part Number: REF6225 Hi Team,
Customer is asking if they don't want any current limit any output, should they leave SS OPEN or short to VIN?
Datasheet Page.3 indicating : short to VIN for max current.
datasheet Page.5 indicating : OPEN can have typical…
Part Number: DAC80508 Other Parts Discussed in Thread: REF6225 , DAC128S085 The exact device I have is DAC80508ZRTER. That is, ZERO/SDO version.
Three questions:
1. What exactly does "Not recommended" means in the Table 1 for the "1/1" Div/GAIN setting…
Other Parts Discussed in Thread: ADS131M08 , OPA388 , OPA2189 , THP210 , OPA189 , OPA392 , REF6225 , ADS131M08EVM I am interfacing my TI ADC ADS131M08 with a sensor that gives out 0.5V to 4.5V signal.
I am looking to find a high precision (ultra low noise, low…
Hi Yuanchen Zhu,
As an example, the image below is taken from the ADS127L11EVM ( https://www.ti.com/tool/ADS127L11EVM ). You can see how the REF6225 is connected for this device to REFP/REFN, and that REFN is connected to AVSS, as are the REF6225 GND pins…
Part Number: ADS1299-4 Other Parts Discussed in Thread: ADS1299 , REF6225 Are there any voltage requirements for using an external reference?
I am thinking of using a REF6225 2.5V reference w/ integrated buffer for ADS1299.
However, the datasheet gives…
