Ultra-Low Power, Single-Channel Integrated
Biopotential (ECG, R-to-R Detection) AFE
MAX30003
General Description
Benefits and Features
● Clinical-Grade ECG AFE with High-Resolution Data
The MAX30003 is a complete, biopotential, analog front-
end 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.
Converter
• 15.5 Bits Effective Resolution with 5µV
Noise
P-P
● Better Dry Starts Due to Much Improved Real World
CMRR and High Input Impedance
• Fully Differential Input Structure with CMRR > 100dB
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
● 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
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.
● High AC Dynamic Range of 65mV
Will Help the
P-P
AFE Not Saturate in the Presence of Motion/Direct
Electrode Hits
● Longer Battery Life Compared to Competing Solutions
• 85µW at 1.1V Supply Voltage
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.
● Leads-On Interrupt Feature Allows to Keep µC in
Deep Sleep Mode with RTC Off Until Valid Lead
Condition is Detected
Applications
● Single-Lead Event Monitors for Arrhythmia Detection
● Single-Lead Wireless Patches for At-Home/
In-Hospital Monitoring
● Chest Band Heart Rate Monitors for Fitness Applications
● Bio Authentication and ECG-On-Demand Applications
• 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
Ordering Information appears at end of data sheet.
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)
