Product details

Single-channel 24-bit AFE in a 15-bump DSBGA

The AFE4404YZPR is a single-channel analog front-end (AFE) from Texas Instruments, delivering 24-bit resolution for precision signal acquisition. It targets applications where one high-resolution measurement channel is sufficient, such as photoplethysmography (PPG) in wearable health monitors or single-lead biopotential sensing.

Supply flexibility and package reality

The 15-bump DSBGA (0.4 mm pitch) demands careful board layout — the exposed bumps under the package require a via-in-pad or micro-via fan-out strategy; a 4-layer PCB with a solid ground plane under the BGA is the safe starting point.

The ROHS3 status covers the full substance restriction list including the four phthalates.

Sourcing and BOM fit

Sourced to order through independent distribution; current pricing and lead time confirmed at RFQ. The 24-bit single-channel architecture makes it a direct fit for BOM positions that previously specified a multi-channel AFE where only one channel was used — no rewiring needed if the pinout is verified against the existing footprint.

Frequently asked questions

Can AFE4404YZPR replace ADS1291IRSMR in an existing design?

Both are 24-bit single-channel AFEs, but the AFE4404YZPR comes in a 15-DSBGA package while the ADS1291IRSMR uses a 4x4 QFN. The pinout and supply voltage ranges differ — the AFE4404YZPR operates from 2 V to 3.6 V on both analog and digital rails, versus the ADS1291's 2.7 V minimum. A board spin is required; they are not drop-in replacements.

What compliance documentation does Texas Instruments provide for AFE4404YZPR?

The device is ROHS3 compliant. Texas Instruments provides the standard RoHS certificate of compliance and material declaration. No UL or IEC certification is listed for this part.
