Part Number: ADS7056 Dear,
I'm having an issues in reading the data from mentioned ADC. It is custom board with several ADCs running the same SCLK,CS but each has its own SDOx. FPGA is controlling SCLK and CS in the manner described in the datasheet of…
Part Number: ADS7057EVM-PDK Other Parts Discussed in Thread: ADS7057 , , ADS7056 , ADS7052 Hi,
We are using a ADS7057EVM-PDK to evaluate ADS7057 ADC. The EVM is connected to a PC through a PHI module. The data is acquired using ADS704X-5XEVM-PDK-GUI installed…
OK then!
Our portfolio tops out at about 3MSPS, which would allow you to capture 8-9 samples. Take a look at the ADS7046 or the ADS7056 and see if they meet your needs.
Hello Aaron,
thanks...
This AN is covering SE ADS7056, while I will using the DE ADS 7047. how the extternal RC filter need to calculate? do I need to connect the +ve pin together to sesor high side while -ve pins to GND of sensor?

Part Number: ADS7046 Other Parts Discussed in Thread: ADS7049-Q1 , ADS7042 Hi Team,
my customer uses ADS7046 in his project. Since we have no EVM for this device, is it possible to modify/equip one of these EVMs to the ADC:

Dear Kim,
Thank you for your feedback. If you system does not need isolation for electrical safety reasons, like we may see with 48Vdc-fed inverters, isolation can help to improve the common mode voltage and common mode voltage transient immunity (CMTI…
Hello Cynthia :
I agree with that sweep from 0 to the full range is a way to measure DNL and INL, but if we reference the document ' SBAU285 ', a user guide for ADS7056 EVM. We can find that a 2-kHz sinusoidal input signal is recommended to measure…
Hello Cynthia :
Thank you for your kindly advice.
I'll replace the input capacitor with pF.
A question about those input capacitor that there is a document said drIving an ADC without driving OPA ( show as Fig.87 ).

Koji,
It turns out that both data sheet are correct, although I understand your confusion as I also thought this was a problem. The two devices operate slightly differently. The ADS7042 has no latency. That is the conversion result for the ADC clocks…
