MAX30003CTI+T

The MAX30003CTI+T by Analog Devices is a complete biopotential analog front-end solution optimized for wearable applications, offering high performance for both clinical and fitness uses. This IC provides a single biopotential channel for ECG waveform and heart rate detection.

Key electrical specifications include a high input impedance greater than 500MΩ, a Common-Mode Rejection Ratio (CMRR) exceeding 100dB, and an effective resolution of 15.5 bits with a noise level of 5µVP-P. It supports a wide DC offset range of ±650mV and operates with low power consumption, drawing 85µW at a 1.1V supply voltage. The device is designed for extended battery life in portable devices.

This ECG front-end IC features built-in protections such as ESD protection and EMI filtering, along with DC leads-off detection and ultra-low power leads-on detection during standby. It includes extensive calibration voltages for self-testing and soft power-up sequencing to prevent transients. The MAX30003CTI+T is suitable for applications like single-lead event monitors, wireless patches for remote monitoring, and chest band heart rate monitors for fitness.

The MAX30003CTI+T is supplied in a 28-TQFN (5x5) package suitable for surface mounting. It operates within a commercial temperature range of 0°C to +70°C, making it a robust choice for various wearable health monitoring systems.
