By Maxim Integrated 209
Maxim’s MAX30002 is a complete single-channel bioimpedance (BioZ) AFE solution for wearable applications. The product is ultra-low power for long battery life and high performance for clinical and fitness applications.
The MAX30002 has ESD protection, EMI filtering, internal lead biasing, DC leads-off detection, ultra-low power leads-on detection during standby mode, and a programmable resistive load for built-in self-test. A soft power-up sequencing allows no large transient power surges are forced into the electrodes. The solution also has high input impedance, low noise, high CMRR, programmable gain, various low-pass and high-pass filter options, and a high-resolution analog-to-digital converter. The bioimpedance channel includes integrated programmable current drive, works with common electrodes, and has the flexibility for two or four electrode measurements. It also has AC lead-off detection and is capable of measuring respiration.
