TDA8925J/N1,112

Overview

The TDA8925J/N1,112 is a switching power stage for a high-efficiency Class-D audio amplifier system. It operates with supply voltages from ±7.5 V to ±30 V and delivers up to 20 W per channel into a 6 Ω load at 10% THD. The device features very low quiescent current consumption and achieves over 94% efficiency. It includes built-in temperature and short-circuit protection with diagnostic output capabilities.

Feature Summary

High efficiency exceeding 94 percent
Integrated overtemperature and short-circuit protection
Diagnostic output for fault reporting
No heatsink required

Applications

Television sets
Home-sound sets
Multimedia systems
Mains fed audio systems

Procurement Notes

Verify the specific ordering suffix J/N1,112 against the manufacturer's latest documentation to confirm package type and compliance status. Confirm product lifecycle status as discontinued or obsolete before finalizing procurement plans. Ensure compatibility with existing PCB layouts designed for the DBS17P package format.

Selection Notes

Select this component for applications requiring a self-oscillating Class-D power stage with minimal external control logic. The wide supply voltage range supports various mains-fed designs. Verify that the thermal resistance characteristics meet the ambient operating requirements without additional cooling infrastructure.

Part Context

This part belongs to the TDA8925 family of power stages manufactured by Philips Semiconductors, now NXP. It serves as the switching element in a two-chip Class-D amplifier architecture, working alongside a control IC to drive loudspeaker loads efficiently.
