ADS1292: 2-Channel EEG amplifier

Part Number: ADS1292
Other Parts Discussed in Thread: ADS1299,

Hello,

For a 2-channle EEG acquisition system, we are currently using ADS1299.

But for the final application the chip is too large and supply voltage is too high for our particular requirement.

So I am considering implementing ADS1292 for the design of the 2-channel low-power and highly miniaturised EEG acquisition solution.

I am thinking adding a JFET input preamplifier.

Would you have a better solution for such an application?

Would you have recommendations if using ADS1292 with a preamplifier (either discrete of integrated)?

With my best regards,

Olivier

    Hi Olivier,

    Thank you for your post. 

    The ADS1292 was optimized for ECG application and may be used for EEG application with a preamplifier. There are a few instrumentation amplifiers from TI that can be used in such applications. Please reach out to the amplifier E2E team for a recommendation with your requirement for the preamplifier stage in your design.  

    Thanks.
