The ECG2_AM1 is a fully functional implementation of a single electrocardiogram (ECG) analog frontend. It consists of input protection, amplification, 60Hz notch filtering, antialiasing, and buffering for direct connection to an analog-to-digital converter (ADC). The module has been designed to offer the user a low noise, low offset, and low power solution in a small package that is compatible with 0.1” pitch breadboards for easy prototyping with a minimum of external analog components.
