Hi Dean,
You could certainly implement the filters on an FPGA, we did something similar to that a few years back before the AMC1210 was released (see the ADS1202 Reference Design).
Hi Xiangyong,
Welcome to our e2e forum! You would need to feed the output of the AMC1304 through a digital filter, built in an FPGA or through the Sigma Delta Filter Module of a processor such as the Delphino class C2000 controllers from Texas Instruments…
Hello Peter,
Yes, I'm planning to use INA240 in inline configuration. And ADS1202 looks like a good choice for measure its output.
Thanks for your consideration
Part Number: AMC1203EVM Other Parts Discussed in Thread: MSP430FR5994 , ADS1203 , ADS1202 , AMC1203 , AMC1200 , AMC1100 Hi,
I am working on a constant current power supply in which i need to measure output current. The current shunt resistor will drop around…
Hi Philipp,
Did you mean the ADS1202? If so, the major difference between the ADS1202 and AMC1204 is that the ADS1202 does not offer any galvanic isolation. Fundamentally though, they are both delta-sigma modulators that provide a bit-stream of data to…
Hello kyt, My recommendation would be to carefully review the following document: "Combining the ADS1202 with an FPGA Digital Filter for Current Measurement in Motor Control Applications" ( www.ti.com/.../sbaa094.pdf) Best regards, Jose
Other Parts Discussed in Thread: ADS1202 Hi,
Im trying to use the VHDL code (sinc3 filter) from

Other Parts Discussed in Thread: AMC1204 , ADS1202 Hi,
I am working with AMC1204 datasheet to design a sinc3filter/decimate in the Altera FPGA. I m using VHDL as the language for coding. I would like to test my design once it is complete. Is there a VHDL…
Pankaj,
I'm not precisely sure of what you are looking for, but do you need a delta sigma ADC, with some modulator out?
You might look at the ADS1202/ADS1203, but there's no digital filter on the output.

Hi Winston,
Welcome to the e2e community! The AMC1305 datasheet describes the implemetation of a digital filter on the output bit stream in section 10. An OSR of 256 should get you a 16-bit word with an ENOB of 13.8 at a data rate of 78kSPS. Some…
