Part Number: ADS131A04 Other Parts Discussed in Thread: ADS131A02 Hello,
I use this device with an analog supply of AVDD = + 2.5V and AVSS = -2.5V. Chapter " 10.1.1 Unused Inputs and Outputs" states that unused analog inputs shall either be left…
Part Number: ADS131A04 Other Parts Discussed in Thread: REF5045 Hello,
I'm designing a design with ADS131A04 for current/voltage protection&metering application.
I plan to use adc @10ks/s sample rate and to fit all the signal dynamic I will need…
Part Number: ADS131A04 Other Parts Discussed in Thread: TPS3850 We have a voltage reference REF3425IDBVR connected to REFEXT input in ADC ADS131A04IPBS and are trying to make this configuration SIL-capable by increasing fault detection. If the voltage…
Hi Sri,
I noticed you set the JP3 jumper to pin 2-3 position, this led to your AVSS to -2.5V, however the AVDD is 3.3V on the EVM by default, so your AVDD-AVSS-=5.8V for the ADC. I'm not sure if this is related to the issue you are facing, however, please…
Part Number: ADS131A04 Hello,
I was in contact with TI ~1 year ago about oscillation problems. We use a suggested crystal and have worked a lot with the load capacitors.
Now I see more customers having problems with this, has TI done some die shrinking…
Part Number: ADS131A04 Hi,
A battery was connected to the analog (ADS131A04) input, and the PCB was gently tapped.
The result of the ADC conversion was a jump far beyond the normal range.
What's happening?
Thanks!
Part Number: ADS131A04 Hello,
i have a question to the selection of load capacitors for ADCs.
In my design i use your ADS131A04 and the quartz ABM3C-16.000MHZ-D4Y-T.
How can i calculate the two load capacitors at the XTAL pins of the device.
Is it right…
Part Number: ADS131A04 Hi,
we use the ADS131A04 in our design and it work. But in every conversion result the status bits are 0x2220 ... Why ?
Here my initialisation : (M0 Vdd | M1 and M2 GND -> 24 Bits)

Part Number: ADS131A04 Other Parts Discussed in Thread: TMS320VC5509A Hi Team, A customer is using TMS320VC5509a to control ads131a04 but was unable to find a clear description about how to read the translation results of ads131 in the datasheet so when…
Part Number: ADS131A04 Hello,
I reed a thread regarding problems with crystal startup. We have discovered that the XTAL input of the ADS131A04 is extremely sensitive.
We used the recommended crystal ABLS-16.384MHZ-L4Q-T, the crystal is placed very close…
