MAX30009ENA+

MAX30009 is a low-power, high-performance bio impedance analog front-end. It complete Bio impedance (BioZ) analog front-end (AFE) solution for wearable applications. It offers high performance for fitness, wellness, and clinical applications, and ultra-low power for long battery life. The BioZ receive channel has electrostatic discharge (ESD) protection, electromagnetic interference (EMI) filtering, internal lead-biasing, DC leads-off detection, DRVN leadoff detection, and ultra-low power lead-on detection during standby mode. The BioZ receive channel also has high input impedance, low noise, high common-mode rejection ratio (CMRR), programmable gain, various low-pass and high-pass filter options, and two high-resolution analog-to-digital converters for simultaneous I and Q acquisition. Application includes wearable fitness, wellness, and medical devices, multifrequency body composition analysers, non-invasive hemodynamic monitors, and automatic external defibrillators.
