Part Number: ADS7851 Hi there,
the figure and table on page 3 of the datasheet shows that:
pin 11 = SDO-A
pin 12 = SDO-B
whereas Figure 52 on page 28 (layout example) shows
Pin 11 = SDO-B
pin 12 = SDO-A
Which is correct? Thanks in advance!
Marvin,
Yes. It is in the library. To access the TI library you can select "Place>PSpice Component > Search". Then find the ADC folder and past the part. You can also download the reference design from the device folder on TI.com and unzip…
Part Number: ADS7851 Hi,
I am using ADS7851 and noticed that in the datasheet the maximum input is 2* Vref or AVdd. I then noticed the VCM is spec'd very tight around 2.5V. If I need to make my common mode voltage 3.3V (or some other voltage other than…
Hello Dino,
Do you know the reason why the customer does not want the input mux? or what the type of end product this will be?
Does the customer only need 4 channels or are they planning to use more than 1 device to create more channels?
If they only…
Part Number: ADS7851 On page 9 of the datasheet (April 2014), figure 2, it shows that the MSB comes out on the third falling edge of SCLK and should be latched by the host on the third rising edge. On page 22, table 2, it shows that the MSB comes out…
Part Number: ADS7851 Hi, I've recently purchased ADS7851
With QFN16 to DIP16 adapter I connected it to Raspberry Pi, trying to communicate via SPI.
However, I'm facing some problems, which might be unique one for this product since ADS7851 doesn't…
Part Number: BEAGLEBK
Hello team,
I asked this on the Precision Data Converters Forum, please see here:
Can I simply connect the SCLK output from SPI1 to the SCLK of SPI0 and set SPI0 as a slave, or is there a specific procedure for this? Also, if SPI0…
Part Number: ADS7851 Other Parts Discussed in Thread: ADS7054 , ADS7056 Hello team,
I'm working on a design that utilizes the ADS7851 and Beaglebone Black for data acquisition. I'm a bit unfamiliar with SPI communication so I am a little confused on how…
Other Parts Discussed in Thread: ADS7851 Hello,
I am developing a SDR receiver with ADS7851 in Altium Designer, but there is no CAD symbol (.bxl file) on ADS7851 page.
Can you prepare it? Or is there any chance to use CAD symbol of similar device?
Thank…
Other Parts Discussed in Thread: ADS7851 , THS4521 Hi, I am developing a SDR receiver as my bachelor thesis. It is my first hardware project, so I got stuck on basics, probably.
Here is expected block scheme:
I will use a SDR concept, which contains an analog…
