SA58672UK,027

Overview

The SA58672UK,027 is a mono filter-free Class-D audio amplifier manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.0 V to 5.5 V and delivers up to 3.0 W into a 4 Ω load at 5 V or 1.7 W into an 8 Ω load at 5 V. The device features a 9-bump WLCSP package with dimensions of 1.66 mm × 1.71 mm × 0.6 mm. Key electrical parameters include a typical supply current of 3.4 mA, a shutdown current of 10 nA, and a fast start-up time of 7.0 ms. It provides high PSRR and differential circuit topology for improved noise immunity.

Feature Summary

• Filter-free operation eliminates the need for external output LC filters.
• Shutdown control minimizes power consumption in standby modes.
• High power supply rejection ratio enhances immunity to noise and RF rectification.
• Integrated thermal and short-circuit protection safeguards against fault conditions.

Applications

• Wireless and cellular handsets
• Personal Digital Assistants (PDAs)
• Portable DVD players
• USB speakers
• Notebook PCs

Procurement Notes

Verify the specific ordering suffix UK,027 corresponds to the 9-bump WLCSP package variant. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the datasheet revision matches the design specifications. Check for any moisture sensitivity level restrictions during storage and handling prior to assembly.

Selection Notes

Select this component when space constraints require a minimal footprint solution for portable audio applications. The WLCSP package offers significant board area savings compared to leaded packages. Consider the 3.0 W output capability into low-impedance loads if higher volume is required. Verify that the system power supply remains within the 2.0 V to 5.5 V operating range.

Part Context

This part belongs to the SA58672 family of mono Class-D audio amplifiers from NXP. The family includes variants such as the SA58672TK, which utilizes a 10-terminal HVSON package. Both variants share identical electrical performance characteristics but differ in physical packaging and thermal dissipation properties. The UK variant specifically targets ultra-compact mobile designs.
