Electrocardiogram (ECG) Amplifying Circuit
Cardiovascular disease has become a very common disease, and with the speeding pace of life and people’s increasing awareness of life standard and health, they need to exam and protect their hearts at any time and to carry out timely treatment in emergency. As shown in the electrocardiogram (ECG) amplifying circuit, it does not only use transformer coupling isolated amplifier 3656 , but also uses a piece of precision operation amplifier OPA177 (offset voltage≤ 10μV ,the offset voltage drift is 0.1 μV / ℃,the open-loop gain is greater than 130 dB, and the static typical current is 1.5 mA).
