This ECG detection circuit is designed using the ISO122 and INA115 components, making it ideal for medical applications. It ensures low input impedance, minimal leakage current, high accuracy in signal detection, and maximum safety for the human body. The signal from the ISO122 is sent to a post-amplifier circuit, which provides both isolation and amplification of the biological signal, along with power supply management. This design helps in effectively reducing electromagnetic interference from the environment and eliminates ground loops, ensuring stable and reliable performance. Whether used in clinical settings or portable monitoring devices, this circuit offers excellent reliability and precision.
