Part Number: AMC1210MB-EVM Other Parts Discussed in Thread: ADS1203 , AMC1203EVM , I try to evaluate ADS1203 ADC in combination with an AMC1210MB-EVM i bought recently. I have built a custom EVM with similar wiring and pinnning as AMC1203-EVM. I have…
Part Number: TMS320F28377D Other Parts Discussed in Thread: AMC1306M25 , ADS1203 Hi,
TMS320F28377D SDFM can support four different modes.
AMC1305L25 , AMC1305M05 .... can support MODE 0.
AMC1306M25 can support MODE 2.
ADS1203 can support all 4…

Kadir,
SDFM is a filter module and as Frank mentioned it take only sigma delta modulated bit streams and these modulated bitstreams come from SD-modulators (which are external to this chip) like AMC1304, ADS1203 etc.
ENOB / resolution you can achieve…
Sana,
1) Yes, you can use GPIO20 / 21 as SD pins without any issues. For generating SDSYNC event, you don't need to configure PWM11A / 11B (oR) use GPIO165 / 166. You just need to configure PWM11.CMPC / CMPD and PWM12.CMPC/CMPD. No external pin connection…
Hideaki,
SDFM (mode2 (or) manchester mode) can decode manchester encoded sigma delta modulated bit stream. ADS1203 SD modulator can provide manchester encoded signal which can fed to F28377D SDFM signal. This can be used along with F28377D control cards…
Hi David,
alright, understand.
Our MCU's could certainly do that as well but in the end what they do internally is probably sample the input signal with the integrated ADC and then calculate and output the PWM signal based on the conversion result…
Hi Urs,
Welcome to our e2e Forum! There are devices like the ADS1202 and ADS1203 which both feature +/-250mV input ranges and are non-isolated, but they come in a slightly larger package. The is also the AMC1035, but that has a significantly higher…
Other Parts Discussed in Thread: ADS1203 Hello,
This question came from " TMS320F28377D - Sigma Delta Filter Module (SDFM), mode 2: Manchester encoded input: Any tools to evaluate the mode? "
I understood that "SDFM mode 2" looks good to be connected…
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,…
