Infineon Digital Audio Power Amplifier IC, IRS2092S, 500W, SOIC-16

The Infineon IRS2092STRPBF is a high-voltage, high-performance, protected digital audio amplifier driver integrated circuit (IC). It incorporates a PWM modulator and comprehensive protection features, enabling the realisation of a complete, robust Class D audio amplifier when paired with two external MOSFETs and a handful of additional components.

Utilising proprietary noise isolation technology, this IC integrates a high-current gate drive stage and a high-speed, low-noise error amplifier on a single, compact silicon die. Its flexible PWM modulator architecture allows for versatile topology implementation, making it suitable for a wide range of audio power applications.

Key Features & Performance

• High Power & Low Distortion: Capable of delivering up to 500W of output power into a 4Ω load, with an impressively low Total Harmonic Distortion plus Noise (THD+N) of 0.01% (measured at 1kHz, 50W).
• Integrated Protection: Features programmable, bidirectional over-current protection with a self-reset function and a programmable preset deadtime to optimise performance and safety.
• Excellent Audio Quality: Engineered with start/stop click noise reduction and high noise immunity for clean audio operation. Its operational transconductance amplifier (OTA) offers a maximum gain of 60dB.
• Robust Design: Rated for supply voltages from 10V to 18V and capable of handling ±100V, with a high switching frequency of 800kHz. It operates reliably across an extensive ambient temperature range from -40°C to +125°C.
• Surface Mount Package: Housed in a compact, 16-pin NSOIC (SOIC-16) surface-mount package, facilitating easy integration into modern PCB designs.

This amplifier driver IC is an ideal solution for designers seeking to build efficient, high-fidelity audio power stages with built-in reliability safeguards.
