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. The bioimpedance channel includes integrated programmable current drive, works with common electrodes, and has the flexibility for 2 or 4 electrode measurements. It also has AC lead off detection.
The MAX30002 is available in a 28-pin TQFN and 30-bump wafer-level package (WLP), operating over the 0°C to +70°C commercial temperature range.
Applications
- Impedance Based Heart Rate Detection
- Respiration and Hydration Monitors
- Single-Lead Wireless Patches for In-Patient/Out-Patient Monitoring
