ANALOG DEVICES MAX30003CTI+ Analog Front End, Biopotential Measurements, 1 Channel, 18 bits, 512 SPS, SPI, 2 V, TQFN-EP-28

MAX30003CTI+ is a complete, biopotential, analogue frontend solution for wearable applications. It offers high performance for clinical and fitness applications, with ultra-low power for long battery life. The MAX30003 is a single biopotential channel providing ECG waveforms and heart rate detection. The biopotential channel has ESD protection, EMI filtering, internal lead biasing, DC leads-off detection, ultra-low power leads-on detection during standby mode, and extensive calibration voltages for built-in self-test. Soft power-up sequencing ensures no large transients are injected into the electrodes. The biopotential channel also has high input impedance, low noise, high CMRR, programmable gain, various low-pass and high-pass filter options, and a high resolution analogue-to-digital converter. Suitable for single-lead event monitors for arrhythmia detection, single-lead wireless patches for at-home/ inhospitable monitoring, chest band heart rate monitors for fitness applications.

• Suitable for bio authentication and ECG-on-demand applications
• Clinical-grade ECG AFE with high-resolution data converter
• Better dry starts due to much improved real World CMRR and high input impedance
• Offers better common-mode to differential mode conversion due to high input impedance
• Minimum signal attenuation at the input during dry start due to high electrode impedance
• High DC offset range of ±650mV (1.8V, typ) allows to be used with wide variety of electrodes
• Longer battery life compared to competing solutions, 85µW at 1.1V supply voltage
• Configurable interrupts allows µC wake-up only on every heart beat reducing the overall system power
• High-speed SPI interface, shutdown current of 0.5µA (typ)
• 0°C to +70°C temperature range, 28 TQFN-EP package
