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: 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…
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 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…
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…
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…
