Sets the input amplifier gain factor. DC bias of ECGP and
ECGN and slow-moving DC drift signals are removed by the
input amplifier, and the differential AC signal is amplified by
this factor before being passed to the PGA and ADC.
The INA can rapidly recover from an overdrive event, such as
a defibrillation pulse. There are two modes of fast recovery:
automatic and manual. In the automatic recovery mode, the
overdrive event is detected when the output of the ECG
measurement exceeds the symmetric thresholds defined by ±
(2048 x ECG_FAST_REC_THRESHOLD). Although the
manual recovery mode is presented as an option in the GUI, it
is a feature that is best deployed in end-application firmware.
Refer to the ‘Fast Recovery Mode’ section of the MAX86178
data sheet for details.
Sets the ECG threshold at which the fast recovery mode
begins to trigger.
Sets the gain factor for the PGA. This is the final gain stage
before the ECG signal is sampled by the ADC.
