概要
Description
MAX30003CTI+T is Maxim Integrated’s (now Analog Devices) ultra-low-power ECG front-end IC designed for wearable and portable monitors. The CTI+T suffix indicates a specific packaging/temperature option for the device.
What it does:
- Provides the essential analog front-end to acquire biopotentials (ECG), including amplification, filtering, and noise rejection.
- Includes functions such as lead-off detection and a right-leg drive to improve signal quality.
- Interfaces to a host microcontroller via a digital serial interface for data transfer and processing.
Why use it:
- Very low power and compact, enabling long-battery wearable solutions.
- Reduces BOM and design complexity by integrating key analog functions.
- Suitable for single-lead or limited multi-lead ECG sensing in wearables, patches, and ambulatory monitors.
What to check:
- Exact features (gain range, bandwidth, lead-off behavior) and whether an internal ADC is included, via the MAX30003 datasheet and the CTI+T packaging note.
