Part Number: ADS7947
Unlike some of TI’s ADC datasheets, the datasheet for the ADS794x series provides no maximum input current specification. This is probably a big hint that I’m approaching my problem the wrong way, but perhaps somebody will give…
Part Number: ADS7947 Hi Team,
We are penetrating ADS7947 at my customer side and find below error from our datasheet's reference sch as below:
Pin 7 is AIN1N which should be connected to GND but not connected to input, while Pin 8, AIN1P should…
Hello,
The t_su1 defines the minimum time that should be present between the CS falling edge and SCLK rising edge, of 3.5ns
In the second format, it seems you are violating this as the CS falling edge and SCLK rising edge are occurring at the same…
Part Number: ADS7947 Other Parts Discussed in Thread: TLE2027 Hello
I, like dale, am using a ADS7947 ADC. It is being used to replace an obsolete ADC (from another manufacturer) in some existing equipment. One of the requirements is that I should make…
Part Number: ADS7947 Hello,
On top of my previous question I got 2 additional questions :
1. Asymmetrial input resistor?
in the datasheet there seems to be a contradiction about the input resistor.
On page 27 it is mentioned :
"The 470pF capacitor…
Hello Abhijeet,
The SCLK=35 MHz and the CSn=2MHz. So acquisition time is somewhat more than 80ns. The band of interest is between 300 and 380 kHz.
Kind regards,
Filip
Part Number: ADS7947 Other Parts Discussed in Thread: ADS7945 , Hi E2E,
Good day!
Do you know the ESD level of ADS7947SRTER?
Thank you for your usual support.
Best regards,
Franz
Part Number: ADS7947 I have a design that uses four ADS7947. All converters are sharing a common clock and CS. There is an FPGA generating the clock and CS signals and reading the individual SDO. Usually it works very well, but once in a while the converters…
Part Number: ADS7947 Other Parts Discussed in Thread: ADS7883 , I'm looking to replace ADS7883. (single ended, rail-to-rail)
My Analog supply voltage is 5V and sample rate is 500 kHz.
The ADS7947 is a pseudo-differential AD.
Will it be suitable…
