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…
Part Number: ADS7947 Hi supporter,
When I use stm32H750 to get data from ADS7947 through spi, I meet a strange problem.
When I use GPIO to simulate SPI com, everything seems fine, I got a smooth curve,
just like the input signal.
BUT, when I use stm32…
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 be…
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: 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 Other Parts Discussed in Thread: OPA365
Hello,
We plan to use the ADS7947 at the IF output of a tuner (R820T2), we want to use it at maximum speed (2MSPS). i have two questions regarding the implementation:
-Is it absolutely required…
Part Number: ADS7947 Other Parts Discussed in Thread: OPA2835 , , OPA365 The datasheet of the ADS7947 mentions in Fig 52 (input driving circuit with opamp) as well as in Fig 53 (input driving circuit without opamp) that R1 should be 5 Ohm. I am looking at…
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 across…
