Description
This TI Verified Design is for Electrocardiography (ECG), the measurement of the electrical activity of the heart, a method that requires a precision analog front end instrumentation gain stage, filtering, and high resolution digital conversion. This design features the methodology for achieving a LEAD I ECG measurement system designed from discrete analog components. Ultra low power is optimized by an instrumentation front end using an OPA2333 and is digitized by the 18 bit ADS8881.
