TFA9891UK/N1/S1Z

Overview

The TFA9891UK/N1/S1Z is a boosted Class-D audio amplifier from NXP Semiconductors, designed for single-channel mono applications. It delivers an output power of 3.7 W into an 8 Ohm load with a total harmonic distortion plus noise (THD+N) of 0.03%. The device operates within a supply voltage range of 4.5 V to 5.5 V and functions across a temperature range of -40°C to +85°C. It is housed in a compact 49-pin WLCSP package.

Feature Summary

Boosted Class-D architecture with integrated speaker boost protection algorithm
High-fidelity audio performance with low THD+N
Compliant with EU environmental standards including ROHS and REACH

Applications

Automotive infotainment systems
Smart audio amplifier implementations
Mono channel audio output stages

Procurement Notes

Verify the specific suffix configuration (N1/S1Z) against current availability as manufacturing status may have changed. Confirm package type matches design requirements. Check for any recent product change notices regarding assembly location or marking updates. Ensure compliance with current environmental directives before integration.

Selection Notes

Select this component for applications requiring a compact, high-efficiency mono amplifier. The WLCSP package suits space-constrained designs. Verify that the 3.7 W output power meets system requirements. Consider the operating temperature range for automotive or industrial environments. Confirm supply voltage compatibility with the host system.

Part Context

This part belongs to the TFA989x series of smart audio amplifiers by NXP Semiconductors. It is specifically engineered for boosted Class-D applications. The series includes variants like the TFA9890UK. The TFA9891UK/N1/S1Z represents a specific configuration within this family, optimized for single-channel use.

Replacement Considerations

Check for direct substitutes within the TFA989x series. Verify pinout and electrical specifications match. Consider the TFA9890UK if dual-channel capability is acceptable. Confirm package compatibility for PCB re-design.
