Other Parts Discussed in Thread: ADS1298
Dear TI team,
EN60601-2-25 §201.12.4.107.2 specifies:
"The ECG shall be capable of recording a +/- 5mV input signal (biphasic polarity applied to any lead).
With an input signal producing a peak-to-valley deflection of 10mV at the center of the effective recording width the recorded amplitude shall not change by more than 5% (+/-500uV) when the recorded signal is shifted over the whole of the effective recording width
This requirement shall be met in the presence of differential and common mode DC offset voltages of +/- 300mV. These offset voltages shall not be applied simultaneously."
Assuming:
a) the ADS1298 is programmed with an input voltage range of +/- 5mV
b) RLD is used
Will the +/- 300mV offset be removed by the RLD or will it hide the useful signal (by "saturating" the op amp) ?
Thanks,
Paul-Alexandre,
