Overview
The TFA9881UK/N1,023 is a mono Class-D audio amplifier manufactured by NXP Semiconductors. It delivers 3.4 W of output power and accepts Pulse Density Modulation (PDM) input signals. The device is housed in a 9-bump Wafer Level Chip-Scale Package (WLCSP9) with physical dimensions of 1.50 mm x 1.28 mm x 0.60 mm. This compact form factor supports integration into space-constrained portable electronic devices requiring high-efficiency audio amplification.
Feature Summary
- Integrates PDM interface for direct connection to digital microphones or processors
- Provides efficient Class-D amplification for extended battery life in portable applications
- Utilizes ultra-compact WLCSP9 packaging to minimize printed circuit board area
Applications
- Portable multimedia players
- Smartphones and mobile communication devices
- Digital voice recorders
Procurement Notes
Verify the specific ordering suffix against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints designed for the WLCSP9 configuration. Cross-reference the part number with current manufacturing status notices to avoid obsolete components.
Selection Notes
Select this component when a mono audio solution with PDM input is required. The choice is driven by the need for minimal board space due to the small footprint. Consider the 3.4 W power rating relative to the speaker impedance and supply voltage constraints of the target design.
Part Context
This amplifier belongs to the TFA988x series of audio solutions from NXP Semiconductors. The series focuses on providing integrated audio processing capabilities within a small form factor. The UK variant specifically denotes the WLCSP9 package option, distinguishing it from other pinout or package configurations within the same functional family.
Replacement Considerations
The TFA9881UK/N1,118 is a documented alternative variant within the same product line. Verify that the reel packaging differences do not impact assembly processes before substitution.
