Shenzhen Better Life Elec S&T BL1860

The BL1860 is a high-performance electrode-based ECG acquisition chip designed to extract and amplify weak electrophysiological signals reflecting cardiac activity from the human body. It is a single-channel weak signal acquisition front-end featuring adjustable gain, adjustable bandwidth, a built-in internal reference, and a low-dropout linear regulator. With its high integration, compact package, and ultra-low power consumption, the BL1860 is well-suited for scalable medical instrumentation, wearable health devices, and other mobile healthcare applications where form factor, power consumption, and total cost are critical considerations.
