MAX30002CWV+

The MAX30002 is a complete bioimpedance (BioZ), analog front-end (AFE) solution for wearable applications. It offers high performance for clinical and fitness applications, with ultra-low-power for long battery life. The MAX30002 is a single bioimpedance channel capable of measuring respiration. The bioimpedance channel 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. Soft power-up sequencing ensures no large transients are injected into the electrodes. The channel 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.

• BioZ AFE with high resolution data converter (17 Bits ENOB with 1.1µVP-P Noise for BioZ)
• High AC dynamic range of 90mVP-P will help prevent saturation in the presence of motion/direct electrode hits
• Longer battery life compared to competing solutions (158µW at 1.1V supply voltage)
• Leads-On interrupt feature allows to keep µC in deep sleep mode until valid lead condition is detected
• High accuracy allows for more physiological data extractions
• 8-Word FIFO allows the MCU to stay powered down for 256ms with full data acquisition
• High-Speed SPI interface
• Shutdown current of 0.58µA (typ)
