Product Details
MAX30003CTI+ - Single-Channel ECG Analog Front End
MAX30003CTI+ from Analog Devices / Maxim Integrated is a single-channel ECG analog front end with R-to-R detection in a 28-pin TQFN with exposed pad, supplied in trays.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
MAX30003 acquires a single biopotential ECG channel and reports R-to-R heart-rate events. The signal chain includes electrode protection, lead detection, programmable gain, conversion, a 32-word FIFO and a high-speed SPI interface.
Key Advantages
Combines ECG acquisition and R-to-R detection in one low-power AFE.
A 32-word FIFO and interrupt outputs reduce host wakeups.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Single-channel ECG acquisition and R-to-R detection AFE
SPI, active-low interrupt outputs and differential ECG input
AVDD/DVDD 1.1 V to 2.0 V; OVDD 1.65 V to 3.6 V; 0 C to 70 C
28-WFQFN Exposed Pad
Package & Footprint
This ordering code uses the 28-WFQFN Exposed Pad package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
MAX30003CTI+T is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Analog Devices lists MAX30003 package and order-code variants for 28-pin TQFN and 30-bump WLP. These footprints are different, so any cross-package sourcing option requires a board and assembly review.
Applications
Captures single-lead ECG waveforms with low-power host wakeup.
Reports beat timing while buffering ECG samples for the host.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
Single-channel ECG acquisition and R-to-R detection AFE
What package is used?
28-WFQFN Exposed Pad
Can the related part be substituted directly?
No. Validate all electrical, mechanical and configuration differences first.
Is the package image ready?
No. The registered package JPG is currently missing.
Engineering Notice
Use the latest manufacturer documentation for schematic, PCB, thermal and production approval. Distributor attributes are useful for sourcing but do not replace the official data sheet.
