Overview
The TDF8590TH/N1S,118 is a high-efficiency Class-D audio power amplifier designed for car audio systems. It features dual channels capable of delivering 2 × 80 W into 4 Ω in Single-Ended (SE) mode or 1 × 160 W into 8 Ω in Bridge-Tied Load (BTL) mode. The device operates over a wide supply voltage range from ±14 V to ±29 V with low quiescent current consumption. It utilizes an HSOP24 package with an internal heat sink and includes comprehensive protection mechanisms such as thermal foldback, overtemperature, and short-circuit protection.
Feature Summary
- Zero dead time switching minimizes distortion and improves efficiency.
- No DC offset induced pop noise at mode transitions ensures silent operation.
- High BTL output power capability up to 160 W into 8 Ω loads.
- Integrated full protection suite including thermal foldback and window protection.
Applications
- Car audio systems
- Dual channel stereo amplification
- Mono bridge-tied load speaker driving
Procurement Notes
Verify the specific ordering suffix N1S,118 against official NXP documentation to confirm packaging details and reel specifications. Ensure compatibility with the HSOP24 package dimensions and thermal requirements for your application design.
Selection Notes
Select this component for applications requiring high power density and efficiency in automotive environments. Consider the differential input configuration and external oscillator synchronization capabilities if multiple amplifiers are used in the same system.
Part Context
The TDF8590TH belongs to the TDF859X series of Class-D amplifiers by NXP Semiconductors. It is engineered for high performance with low power dissipation, making it suitable for space-constrained automotive audio installations where heat management is critical.
Replacement Considerations
Consult NXP datasheets for direct pin-compatible alternatives within the TDF859X family. Verify electrical parameters and thermal characteristics when substituting with other Class-D amplifiers.
FAQ
How is the switching frequency determined?
The switching frequency is set by an external resistor connected between the OSC pin and VSSA, typically around 310 kHz with a 30 kΩ resistor.
What happens during a short-circuit condition?
The OverCurrent Protection (OCP) limits the output current to 8 A. If the condition persists, the amplifier shuts down and attempts to restart every 100 ms.
