Hi Stefan,
We have not observed a failure similar to this resolve by soldering/desoldering, but there are other issues with other devices that have shown to disappear in this way. Yes, it would still be useful to get this unit back and deprocess it…
Part Number: ADS7955-Q1 Other Parts Discussed in Thread: ADS7955 Hi there,
I selected ADS7955-Q1 for my application due to cost and temperature grade of 125C. For this ADC, my application consists of measure 6 battery cells (ranging from 10.5V to…
Part Number: ADS7955 Are internal pull-up or pull-down resistors present on the GPIO pins of the ADS7955? If not, is it permissible to allow unused GPIO pins to float, or should they be pulled to a known voltage level?

On pg. 7 of the ADS7955 datasheet, there is a note for the NC pins that states "Pins internally not connected, do not float these pins". Should these pins be tied to ground or some…
Part Number: ADS7955 Hi Team,
Could you help check below questions about the td2 of ADS7955 SPI?
My customer got td2=33.2ns on their board which was much higher than the MAX of td2(17ns) for 5V power supply,the SCLK=1MHz and SDO connected with 50pf…
Other Parts Discussed in Thread: ADS7955-Q1 Hi,
we are planning to use the 8ch devices of the ADS795x Familiy in an automotive application. Its a module design, so we plan to interchange the 8bit, 10bit and 12bit version depending on requirements. …
Hi Daniel,
The ADS7955 (8ch) TSSOP device pin out is compatible with the other ADS79xx devices in the family (12ch and 16ch versions). These pins correspond to the unused channels and are not connected internally. The recommendation is to tie these…
Other Parts Discussed in Thread: ADS7955 Hello,
Please let me know the output code about ADS7955 on the below conditions.
+VA=5V or 4V
Vref =2.5V
Range 2
Analog input =2.5V
In this case, output code will be same on each +VA=5V or 4V…
Other Parts Discussed in Thread: ADS7955 Hello,
Please let me know the behavior of ADS7955.
Vref is set to Range 2 then VA falling to under the 2*Vref.
In this case, Input range(max) becomes the VA.
There is not other problem.
Is my understanding…
