Hi team,
for a ECG acqusition system, the input signal is only 50uV, how can we acquire such a precision signal. can you give me a guidance?

the 50 uV is AC sine rather than the DC voltage, do we need a buffer for the ADC input ,if so, pls give me some guidance on this
Hi Eric Liu (SZ-FAE),
Can you please respond to my query in the Notes section of the Thread Tracking Toolkit?

Hi Bryan,
I have responded to you.
BTW,
do you have any good papers or tools can be shared with me to develop the precision signal chain?
Just like the analog engineer calculator
Hi Eric Liu (SZ-FAE),
I do not see the information I requested, I will email you

Hi Eric Liu (SZ-FAE),
Thanks for providing the requested information
Measuring a very low voltage signal for ECG requires low-noise components (gain amplifier, ADC, reference). We have some integrated solutions for ECG measurements as shown in the image below
For a discrete signal chain you might consider something like THP210+ADS127L11
Since this is a fairly general question, let me know what else specifically we can help you with
