TFA9895BUK/N1Z

Overview

The TFA9895BUK/N1Z is a high-efficiency Class-D audio amplifier manufactured by NXP Semiconductors. It features an integrated boost converter capable of generating up to 10V, enabling high output power into low-impedance loads. The device supports digital audio interfaces including I2S and TDM, allowing for direct connection to digital signal processors or microcontrollers. Designed for mobile and portable applications, it offers high sound quality with low total harmonic distortion plus noise (THD+N). The component is available in a compact WLCSP package, facilitating space-constrained designs.

Feature Summary

• Integrated high-voltage boost converter for driving speakers without external inductors in some configurations
• Digital audio interface support for I2S and TDM protocols
• High efficiency Class-D architecture minimizing power consumption and heat generation
• Compact Wafer Level Chip Scale Package (WLCSP) for small form factor integration

Applications

• Smartphones and mobile phones
• Portable smart speakers
• Tablets and handheld devices
• Voice-controlled assistants

Procurement Notes

Verify the exact suffix 'N1Z' against official NXP documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding pin definitions and thermal requirements. Confirm end-of-life status if sourcing from secondary markets.

Selection Notes

Select this component when a compact, digitally controlled audio solution with integrated power boosting is required. Compare against similar NXP TFA98xx series parts for specific interface or power output needs. Verify that the target application can accommodate the WLCSP package type and associated PCB manufacturing constraints.

Part Context

This part belongs to NXP's TFA98xx family of high-performance audio amplifiers. These components are widely used in consumer electronics requiring high fidelity and power efficiency.
