Ttp321 special chip for ECG detection
Summary
Ttp321 is a special chip for human ECG detection, which is made by CMOS technology. Its peripheral devices are greatly reduced,
It saves space, cost and debugging time, and improves the reliability of the whole machine. Can be widely used in hand-held sports equipment
Such as treadmill.
