Part Number: AMC1210 Other Parts Discussed in Thread: ADS1205 Hello I use the AMC1210 chip paired with the ADS1205 to measure the rotation angle of the transformer(RESOLVER). I have the following questions: 1) Can I get the initialization order of the…
Sounds good. Based on your experience, for resolver application, is this scheme (shown in reference design TMDSRSLVR) a sound design (compared with designs based on PGA411 or AMC1210+ADS1205, etc.)? Thanks.
Part Number: ADS1204 Other Parts Discussed in Thread: ADS1205 , , ADS1209 , ADS1220 , ADS1232 , AMC1204 Hi,
I would use delta sigma modulators with load cell. i found no reference design using modulators with load cells, Is there a reason?
For my application…
Hi Howard,
Yes, with additional oversampling, you can get higher resolution - but that comes at the cost of speed, more sampling means lower throughput so you have to strike a balance. For non-isolated modulators, there are parts like the ADS1201, ADS1202…
Keith,
Thanks so much for the reply.
Thank you for the suggestion. We added a 47pF cap on the FORMAT pin but unfortunately it did not change the 1/4096 signal shape enough to provide any significant decrease (>2dB) in the signal that is being radiated…
Part Number: AMC1210 Other Parts Discussed in Thread: ADS1205 Tool/software: Code Composer Studio Hi,
I am using AMC1210 with ADS1205 for resolver decoding as in the guidance:

Other Parts Discussed in Thread: TMS320F2812 , ADS1205 I am using a C2000 series TI DSP and I have a problem: When the temperature is high (DSP package temp around 80C), sometimes the DSP does not correctly receive SPI messages. At low temperatures the…
Hello Tom, I solved the problems. It depended on the wire. The wire was to bad for this application. Means too much noise coupling.
Now I use a chip based on CMOS.
My question is:
The AMC1305 can only work with a cycle speed of 5 -20 Mhz, but my AMC1210EVM…
Other Parts Discussed in Thread: ADS1205 , AMC1210 , AMC1200 , AMC1210MB-EVM , OPA1632 our customer is evaluating ADS1205 and AMC1210 as the AFE for resolver. customer use TS2640N321E64 RESOLVER. the input voltage requirement is 7Vrms as below table. but AM…
Nischal,
I'm not really familiar with Avago's line, but it looks like the HCPL-786J is just the modulator. As you mention, it puts out a one bit data stream with a 1's density proportional to the analog input that it's measuring.
The…
