Hi!
I am engaged in the research work concerning ECG and I am interested in the use of ADAS1000 for the purpose of ECG acquisition in high frequency and high resolution domains. As I understand, ADAS1000 is intended primarily for standard ECG applications,

So, I have the following questions:

1. Is it possible to obtain high-frequency signal within 100 and 1000 Hz? I suppose, this can be done by changing internal analog filters characteristics or intrioducing external analog high-pass filter.

2. Hgh-frequency ECG components have lower amplitude, thus how can it be additionally amplified to maintain the resolution of 18 bit?
