Product Overview
The ZSBM100X series is a low-power, multi-channel ECG analog front-end (AFE) designed for medical and high-end sports and health analysis applications. Built on a foundation of superior signal quality, it combines excellent analog performance with flexible system-level configurations and is highly integrated with the features required for professional ECG systems. It is designed to help customers easily build scalable ECG systems from 1 to 12 leads with a smaller form factor and lower power consumption, enabling applications such as ambulatory ECG (Holter) monitoring, patient monitoring, and scientific athletic training.
Core Value
Signal Quality
Low noise floor of 0.8µVrms ensures signal purity and diagnostic value.
Highly Integrated System
Large internal FIFO and data compression reduce external storage pressure and transmission power.
Flexible Architecture
Innovative signal routing switch allows flexible configuration of 1- to 12-lead systems.
Low-Power Design
Operating power consumption of only 0.2mW per channel, perfect for portable monitoring devices.
High-Precision ADC
3 independent high-resolution channels support up to 16ksps sampling rate and 24-bit output.
Interference Resistance
Integrated EMI filters at the input effectively suppress high-frequency RF noise.
