Features & Applications

IRAUDAMP7S reference design is a two-channel Class D audio power amplifier that features output power scalability. It offers selectable half-bridge (stereo) and full-bridge (bridged) modes.This reference design demonstrates how to use the IRS2092 Class D audio driver IC, along with IR’s digital audio dual MOSFETs, such as IRFI4024H-117P, IRFI4019H-117P, IRFI4212H-117P and IRFI4020H-117P,on a single layer PCB. The design shows how to implement peripheral circuits on an optimum PCB layout using a single sided board.

The IRS2092(S) is a high voltage, high performance Class D audio amplifier driver with PWM modulator and protection. In conjunction with two external MOSFET and a few external components, a complete Class D audio amplifier with protection can be realized.International Rectifiers proprietary noise isolation technology allows high current gate drive stage and high speed low noise error amplifier reside on a single small silicon die. Open elements of PWM modulator section allow flexible PWM topology implementation.

Features:

  • Output Power: Scalable output power from 25W- 500W 
  • Residual Noise: 200 μV, IHF-A weighted, AES-17 filter
  • Distortion: 0.007 % THD+N @ 60W, 4 Ω
  • Efficiency: 90 % @ 500W, 8 Ω, Class D stage
  • Multiple Protection Features:
    • Over-current protection (OCP), high side and low side MOSFET
    • Over-voltage protection (OVP)
    • Under-voltage protection (UVP), high side and low side MOSFET
    • DC-protection (DCP)
    • Over-temperature protection (OTP)
  • PWM topology: Self-oscillating PWM, half-bridge or full-bridge topologies selectable

Applications:

  • AV receivers
  • Home theater systems
  • Mini component stereos
  • Powered speakers
  • Sub-woofers
  • Musical Instrument amplifiers
  • Automotive after market amplifiers
