Infineon Technologies IRAUDAMP7 Audio Amps Reference Design
Infineon IRAUDAMP7 Audio Amplifiers Reference Design demonstrates a class D audio amplifier above 25W per channel. With a power range from 25W to 500W, the Infineon IRAUDAMP7 Ref Design 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 IRInfineon 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.
