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

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)
