Hello TIer,

I would like to choose one AD for my system. Goal： sample rate 10Hz, high SNR, >22bits valid,

I think ADS128x are good choice. But how about LTC2500-32?

Thanks

Yes, I can see this table in TI web. But, are they the same ?
LTC2500 is from ADI.
Thanks.

Hi ,

Thank you for using e2echina forum.

They have many differences. Check the LTC2500-32 datasheet. Its maximum sampling frequency fSMPL(MAX) = 1Msps; typical SNR value is 104dB; resolution value is 32bit. Advantages and disadvantages are judged by relative application situations. Please select the appropriate chip according to the system application.

Best Regards,
Amy
