Moss launches Maxim MAX30004 bio-potential simulation front-end boosts wearable medical care for health at any time
Mouser Electronics, a prominent distributor in the semiconductor and electronic components industry with a strong focus on new product introductions (NPIs), has begun shipping the Maxim Integrated MAX30004 Biopotential Analog Front End (AFE). This AFE is specifically designed as a single-channel biopotential heart rate monitoring solution tailored for wearable medical applications. It serves as an ideal choice for heart rate chest straps and single-lead wireless heart rate patches, providing a seamless way to monitor heart rates without needing to extract or process ECG data during intense physical activities.
This advanced AFE from Maxim Integrated offers a single biopotential channel capable of measuring the RR wave spacing of heartbeats to accurately determine heart rate. Equipped with robust features such as electrostatic discharge (ESD) protection, electromagnetic interference (EMI) filtering, and DC lead-off detection, it ensures reliable performance under various conditions. The MAX30004 also includes a wide range of calibration voltages for its built-in self-test feature, ensuring accurate measurements. Additionally, its soft power-up sequence minimizes any potential large transients injected into the electrode.
The fully differential input architecture of the MAX30004 boasts an impressive common-mode rejection ratio (CMRR) exceeding 100 dB and a high input impedance of over 500 MOhm, which significantly enhances common-mode to differential-mode conversion. Its lead-on current of just 0.7 mA enables the microcontroller to remain in a deep sleep mode even when the real-time clock is powered down, waking only upon detecting a valid lead condition. Furthermore, configurable interrupts allow the microcontroller to activate only during each heartbeat, further reducing overall system power consumption.
With a DC bias range spanning up to ±650 mV (1.8 V typical), the MAX30004 supports compatibility with a wide array of electrodes. Its ultra-low power consumption, standing at merely 85 mW at 1.1 V, ensures extended battery life compared to competing solutions. These attributes make the MAX30004 a standout choice for developers aiming to create efficient, long-lasting wearable health monitoring devices.
In summary, the MAX30004 AFE not only simplifies the design process but also enhances the efficiency and accuracy of heart rate monitoring systems. Whether you're developing a heart rate strap or a wireless patch, this AFE provides the precision and reliability needed for modern wearable medical applications.
