Part Number: ADS7955-Q1 Other Parts Discussed in Thread: ADS7955 , REF5025 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…
Part Number: ADS8509 Other Parts Discussed in Thread: ADS7955 , ADS7809
Hi Experts,
I would appreciate it if you can help me clarify if the NC Pin for the device ADS8509 SSOP-28 package can be left floating or connected to the ground.
I already checked…
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?
Part Number: ADS7955 Other Parts Discussed in Thread: ADS7953 , ADS7951
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…
Hi David,
Ideally the reference and AVdd/DVdd supplies are up and stable before applying AINx. If you limit the current to ~1mA on the analog input of the TLV1570, you should not damage the device. The closest we have to this in a newer device would be…
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.
Now…
Other Parts Discussed in Thread: ADS7955 Hi E2E,
I have quick questions to the ADS7955SDBT converter :
1. For pins 15 and 16 the datasheet says "Pins internally not connected, do not float these pins". What should I do with them - connect to ground? Anyway…
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.
Is my understanding…
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 correct…
