It comes in a 28-WFQFN with exposed pad (also listed as 28-TQFN, 5x5 mm), a package that is hand-solderable with a hot-air station or reflow oven — the exposed pad needs a good thermal via pattern under it to pull heat away from the die. ## What the package means for your board The 28-WFQFN exposed pad demands a solid thermal land on the PCB — the datasheet's recommended footprint includes a central pad connected to ground with multiple vias to the inner planes. Without that, the die overheats and the analog performance drifts. Surface-mount assembly is standard reflow; the 5x5 mm body is small enough for a compact wearable but large enough to route two layers if you keep the traces short to the decoupling caps. ## Sourcing and compliance at a glance ROHS3 compliance covers the EU RoHS exemption list through 2024; the part is also free of the six original restricted substances plus the four phthalates.","metaTitle":"MAX30003CTI+ ECG Front End, 28-TQFN, Active","metaDescription":"Analog Devices MAX30003CTI+ ECG front end in 28-TQFN (5x5 mm).
