Part Number: ADS8556 Tool/software: Dear Specialists,
My customer is considering ADS8556 and has a question.
I would be grateful if you could advise.

We have a question about Figure 2. Serial Operation Timing Diagram (All Three SDOs Active) on page…
Part Number: ADS8556 Hello, I am inquiring on the change in capacitance on REFC_x (A,B,C) with a 10uF X7R 10V capacitor in 0603 package.
With a 3.3V DC BIAS, the capacitance drops to 6.1uF.
Is it acceptable to use this part with this change in capacitance…
Part Number: ADS8556 Tool/software: In the design notes AVCC capacitor selection can be 0.1uF or 1uF (better noise immunity) each pin and one 10uF. The 10uF can be eliminated with use of 1uF caps on each pin.
Currently, AVCC in the design is 5V and hence…
Hi Jonathan,
Hm. Looking at your schematic again, it looks like REFIO is grounded, so you would want internal ref to be enabled. Could you set C25 = 1?
Does the SDO_x data match your expected conversion results? What about when you set C17 = 0? Could…
Part Number: ADS8556 Hi team,
Customer has two questions as below.
- Couldy you tell the output type of BUSY/INT-pin? Is this open-collector?
- In customer schematic, the pin is pulled up now. How should they deal with the pin?
Regards,
Noriyuki Tak…
Part Number: ADS8556 Hello guys,
One of my customers is going to use 10pcs of ADS8556 per their own board.
At this moment, they have the following question for PCB layout design. Could you please give me your reply?
Q. ADS8556 datasheet has layout example…
Hi Dale,
Thank you very much for your reply and I'm sorry to be late my response.
I heard about their calibration way from the customer. They implement high accuracy voltage reference for ADC input calibration on their own board. Before just ADC measuring…
Part Number: ADS8556 Hi,
A customer asked us about the timing chart shown in Fig. 2 when using Auto-NAP. I would like to know what changes in timing in the case of AUTO-NAP.
As far as I look at the datasheet, I understand that the Auto NAP timing simply…
