Part Number: ADS7945 Tool/software: In my customer's application, this pin is set to high-Z at all times due to an oversight. They don't want the chip to inadvertently go into power-down mode if PDEN goes high during a CS rising edge.
Are there internal…
Part Number: ADS7945 Other Parts Discussed in Thread: ADS7954 Hi,
I have connected a separate digital supply and a separate analog supply to DVDD and AVDD respectively. The digital supply is always connected to ADS7945 while the analog supply is normally…
Part Number: ADS7945 Hi,
I have some questions.
1. Channel Selection
CH SEL can be toggled at any time during the window specified in Figure 77 of datasheet.
But TI recommend to select the desired channel after the first SCLK rising edge and…
Hello Chase,
The basic connections you've shown to the ADS7945 are correct, but there's admittedly not much shown around the device in terms of what's connected to the inputs. Here are some notes based on the schematic and your comments.
1.) We recommend…
Hello HC,
Welcome to E2E forum.
ADS7945 only has GND (pin1), REFGND (pin 4), AINx_GND (pin 6and 7), what the datasheet recommends is using a solid common ground plane, GND and REFGND can be directly connected to common ground plane on second layer…
Part Number: ADS7945 Hi team,
Looking at the DEVICE OPERATION of 16-clock mode in the datasheet, SDO is kept LOW durind 15 and 16 cycle of SCLK. However, customer found that SDO is pulled HIGH at 16 cycle of SCLK. Is this a correct behavior?

Part Number: ADS7945 Other Parts Discussed in Thread: ADS7946 Hello,
I am simultaneously sampling two differential signals with tho ADS7945s sharing a single chip select. I would like to use a single REF5030 to drive the reference input of both ADS7945s…
Hi Tony -
I'm more into the actual application of parts rather than the marketing of them. I do know that min/max values drive production test time, which drives costs. Get some sample of the ADS7945 and try them out. I think you'll be happy with the…
Thanks for the link. I followed all the steps and so it should work, but I still get the same error during MMB0 Driver Installation.
Please advise.
Thanks,
