IR IRAUDAMP7 Audio Amps Reference Design

International Rectifier IRAUDAMP7 Audio Amplifiers Reference Design demonstrates a class D audio amplifier above 25W per channel. With a power range from 25W to 500W, the IRAUDAMP7 offers a high degree of scalability on a single layer PCB.

The IRAUDAMP7S two-channel, 120W half-bridge design provides 91 percent efficiency at 120W in Class D stage, 8Ω, and a THD+N of 0.005% at 1 kHz, 60W, 8Ω, (both typical). The IRAUDAMP7D features IR’s IRS2092 protected digital audio driver IC in a DIP16 package together with through-hole components while the IRAUDAMP7S features the IRS2092S in an SOIC package with surface-mount components.

The IRAUDAMP7 series incorporates critical protection features including over-current protection, over-voltage protection, under-voltage protection, DC-protection, and over-temperature protection. Housekeeping functions include a ±5V supply for analog signal processing for the preamplifier and a +12V supply (Vcc) referenced to -B for the Class D gate driver stage.

IRAUDAMP7D Features:
  • 250 W x 2 channels, (THD=1%, 1kHz, 4 Ohms)
  • 0.05% THD+N distortion @ 120W, 4 Ohms
  • Residual noise 200 µV, IHF-A weighted, AES-17 filter
  • All through-hole components on single layer PCB
  • OCP, OVP, UVP, DC protection & OTP
  • Half bridge/ full bridge selector
  • Featuring IRS2092 Gate Driver IC and IRFI4019H MOSFETs
