Analog Devices Inc./Maxim Integrated MAX30004CWV+T

MAX30004 combines a differential biopotential input, instrumentation amplifier, programmable gain, anti-alias filtering, 18-bit sigma-delta conversion, digital filtering and on-chip R-to-R detection. It can report heart-beat timing through configurable interrupts so a host does not need to continuously process the raw waveform for basic heart-rate monitoring. SPI provides configuration and data access.

The manufacturer specifies a 30-bump WLP for MAX30004CWV+T, with package code W302L2+1 and a nominal 2.7 mm × 2.9 mm bump-side-down drawing. The LCDChip database classifies this part as 30-WFBGA, WLBGA; its package registry normalizes that category to 30-WFBGA. These names must not be assumed dimensionally interchangeable. Verify the manufacturer's WLP outline and land pattern before PCB use.

Layout checks

• Use the manufacturer W302L2+1 bump map and package outline, not a generic BGA footprint.
• Confirm bump-side-down orientation and A1 location.
• Route the differential electrode inputs symmetrically and protect them with a system-specific input network.
• Place supply, reference, high-pass and PLL capacitors according to the data-sheet pin guidance.

The registered 30-WFBGA JPG is missing locally. Package-category equivalence and the visual asset require verification before publication.

The following bump coordinates are from the manufacturer's WLP pin-description table, viewed bump-side down.

Also review VREF, VCM and VBG capacitor requirements and every remaining bump in the complete pin table; do not rely on these functional groups as a complete netlist.

Values retain the manufacturer's stated supply, temperature and operating-mode qualifications. A typical value is not a guaranteed maximum; absolute-maximum limits are not normal operating ratings.

MAX30004CWV+ is the manufacturer's same WLP order code without the tape-and-reel suffix; verify packaging and procurement requirements before treating it as a suitable purchase alternative. Other biopotential AFEs require comparison of electrode-interface protection, channel architecture, R-to-R algorithm, sample rate, supply rails, host protocol, bump map, land pattern, software behavior and qualification. No unverified LCDChip internal alternative link is provided.

The current Analog Devices product page lists MAX30004CWV+T as a WLCSP/WLP part. The MAX30004 Rev. 1 data sheet supplies the electrical characteristics, WLP bump functions and package code used in this description; its suffix note identifies T as tape and reel. The LCDChip package classification requires a separate footprint-equivalence check.

Confirm the full MAX30004CWV+T order code, 30-bump WLP form, package code, reel labeling, lot traceability and handling condition against current manufacturer records. This description does not certify any individual unit or a complete sensing system.

Use the manufacturer's current pin, electrical and application documentation for the complete design. A human-contact or medical application needs independently engineered electrode protection, isolation, verification and applicable regulatory assessment. The registered package JPG is absent and the database's BGA wording has not been reconciled with the manufacturer's WLP definition; publication must wait for those checks.
