MAX30003
Overview
The MAX30003 is a single-channel integrated biopotential Front-End (AFE) designed for clinical-grade ECG and R-R interval detection. It features a high-resolution data acquisition system with ultra-low power consumption, making it ideal for long-term battery-operated monitoring. The chip includes built-in ESD protection, EMI filtering, and leads-off detection to simplify custom PCB layout.
Why Choose This Part
The MAX30003 excels in power efficiency, drawing only 85 microwatts at a 1.1V supply, which significantly extends the runtime of wearable devices. Its high CMRR of 115dB and integrated R-to-R detection algorithm offload intensive signal processing tasks from the host microcontroller.
Applications
Getting Started
Engineers should begin with the MAX30003EVKIT evaluation board to tune the analog filters and test signal quality before migrating to a custom PCB. Firmware development typically involves using the SPI interface to configure internal registers and handle the FIFO-based data interrupts.
