Denis,
One question should your read of the data bus command D15_D0_IN() not come after you pull RD low? Otherwise you are reading the output bus when it is inhibited.
If modifying the read doesn't work can you please try and send scope or Logic Analyzer…
Hello
1. The VIH/VIL of SPI input support hysteresis or not ?
2. Below is AD2S1210 angular and velocity error.
Error range is -0.53~+0.53 degree Is it correct?
Error range is -58.56~+58.56 rpm. Is it correct?
BTW, has any other factor to cause…
Hi,
I have an EVAL-AD2S1210SDZ and the accompanying daughter board EVAL-SDP-CB1Z for reading data from a resolver. Ultimately, I would like to route the position data from the AD2S to an FPGA (specifically using NI PXI-6221 with terminal block SB-68A…
Rajeev,
Please see my responses below.

The datasheet of AD2S1210 is not specifying min/max against SPI Clock similar to other parameters. I assume it as max limit. Is that correct?
Please refer to the fsclk parameter on page…
Questions:
1. When the interference is strong, the excitation signal disappears, as shown in the figure. Under what circumstances will the excitation signal disappear?
2. The datasheet does not give the reset low-level time during normal operation. Then…
Hi,
I am looking for drive capability from REFOUT pin of AD2S1210-EP.
Thanks & Regards,

技术人员您好！，我现在在调试AD2S1210芯片，我想问一下这款芯片的四路输入信号:sin、\sin、cos、\cos，能否将其两辆差分之后输入，即sin、\sin差分得到2sin，cos、\cos差分得到2cos。然后将2sin接到芯片的sin脚，2cos接到芯片的cos脚，芯片的\sin、\cos直接接地。上面的方案能行吗？
Hello,
I have been using AD2S1210 evaluation board with TI F28379D launchpad and control card. The default Excitation gains are 1.54 and 0.866 on 7.2 V peak to peak signal provided by the chip. I changed the gain to 2.74 by soldering 27.4 kOhm resistor…
