Key Features
- Clinical-Grade ECG AFE with High-Resolution Data Converter
- 15.5 Bits Effective Resolution with 5µVP-P Noise
- Better Dry Starts Due to Much Improved Real World CMRR and High Input Impedance
- Fully Differential Input Structure with CMRR > 100dB
- Offers Better Common-Mode to Differential Mode Conversion Due to High Input Impedance
- High Input Impedance > 500MΩ for Extremely Low Common-to-Differential Mode Conversion
- 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
- High AC Dynamic Range of 65mVP-P Will Help the AFE Not Saturate in the Presence of Motion/Direct Electrode Hits
- Longer Battery Life Compared to Competing Solutions
- 85µW at 1.1V Supply Voltage
- Leads-On Interrupt Feature Allows to Keep µC in Deep Sleep Mode with RTC Off Until Valid Lead Condition is Detected
- Lead-On Detect Current: 0.7µA (typ)
- Built-In Heart Rate Detection with Interrupt Feature Eliminates the Need to Run HR Algorithm on the μController
- Robust R-R Detection in High Motion Environment at Extremely Low Power
- Configurable Interrupts Allows the µC Wake Up Only on Every Heart Beat Reducing the Overall System Power
- High Accuracy Allows for More Physiological Data Extractions
- 32-Word FIFO Allows You to Wake Up µController Every 256ms with Full ECG Acquisition
- High-Speed SPI Interface
- Shutdown Current of 0.5µA (typ)
Applications/Uses
- Bio Authentication and ECG-On-Demand Applications
- Chest Band Heart Rate Monitors for Fitness Applications
- Single Lead Event Monitors for Arrhythmia Detection
- Single Lead Wireless Patches for At-Home/In-Hospital Monitoring
Description
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 analog-to-digital converter. The biopotential channel is DC coupled, can handle large electrode voltage offsets, and has a fast recovery mode to quickly recover from overdrive conditions, such as defibrillation and electrosurgery.
The MAX30003 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.
