关键特性
Heart Rate Detection with Interrupt Feature Eliminates the Need to Extract and Process the ECG Data on the Microcontroller
Robust R-R Detection in High Motion Environment at Extremely Low Power
Clinical-Grade Biopotential 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负责人MAXIM PM 张经理1372421 2401
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 Keeps µC in Deep Sleep Mode with RTC Off Until Valid Lead Condition is Detected
Lead-On Detect Current: 0.7µA (typ)
Configurable Interrupts Allows the µC Wake-Up Only on Every Heart Beat Reducing the Overall System Power
High-Speed SPI Interface
Shutdown Current of 0.5µA (typ)
