Key Document
Description
This circuit is designed to condition and digitize an electrocardiogram signal output from the integrated PACE_OUT buffer on the ADS129x to detect artifacts of an artificial pacemaker. This circuit includes an op amp which serves as a signal conditioner and input driver for a fast-sampling SAR ADC.
Features
- Allows detection of pacemaker pulses as small as 2 mV and as narrow as 0.5 ms when used with the ADS129x
- Small footprint
- Flexible front-end gain and sample rates
- Tested and includes theory, component selection, simulation, PCB design, measurement details
