Overview
The TDA8932BTW/N2,518 is a high-efficiency Class-D audio amplifier manufactured by NXP Semiconductors. It features two independent half-bridges with full differential inputs, supporting mono full-bridge (BTL) or stereo single-ended (SE) configurations. The device operates on an asymmetrical supply voltage ranging from 10 V to 36 V or a symmetrical supply of ±5 V to ±18 V. It delivers continuous output power of 2 × 15 W in stereo SE mode at 4 Ω or 1 × 30 W in mono BTL mode at 8 Ω. The package is HTSSOP32.
Feature Summary
- High efficiency and low-power dissipation design
- Thermal foldback and overtemperature protection
- Full short-circuit proof across load and supply lines
- Switchable internal or external oscillator for master-slave synchronization
Applications
- Flat panel television sets
- Flat panel monitor sets
- Multimedia systems
- Wireless speakers
- Mini and micro systems
Procurement Notes
Verify the specific ordering suffix /N2,518 against official documentation to confirm packaging details and environmental compliance status. Confirm component availability as this product line may be discontinued. Ensure compatibility with existing thermal management designs given the HTSSOP32 package constraints.
Selection Notes
Select this component for applications requiring high efficiency without external heat sinks under typical music signals. Consider the thermal foldback feature for maintaining output power at higher temperatures. Verify that the application board provides sufficient copper area for natural convection cooling to maximize performance.
Part Context
This part belongs to the TDA8932B series of Class-D audio amplifiers. It is designed for portable and fixed audio applications where space and thermal constraints are critical. The device integrates advanced protection circuits and differential inputs to ensure robust operation in noisy environments.
Replacement Considerations
Check for direct replacements within the TDA8932 family such as TDA8932BTW/N2 variants. Verify pinout and electrical specifications match before substitution.
