Part Number: ADS1293EVM
Other Parts Discussed in Thread: ADS1293

Tool/software: WEBENCH® Design Tools

Hello sir am using ads1293 evm , but it default set to 24 bit Resolution , but I'm need onely 10 bit resolution, so how to configure the ads1293 to 10 bit, is possible .

    Rakesha,

    Unfortunately this is impossible using the EVM software. However if you develop your own firmware, you can read each of the data registers individually. Figures 79-81 in the ADS1293 datasheet show the data registers. If you want lower resolution, you could read one or two of the registers instead of all 3. This is not possible in loopback mode, though.

    Hello Rakesha,

    This is will not be possible using the EVM software, like I mentioned above. What I indicates as a way to reduce the resolution is only possible if you develop your own system (hardware, firmware, software, etc.). If you are using the EVM, can you not collect the data in all 24 bits and then simply ignore the LSBs that you do not need later?

    Regards,
