Class D audio driver IC integrates two channels in small footprint

International Rectifier has introduced the IRS2052M Class D two-channel audio driver IC for high-performance home theater systems and car audio amplifiers. The 200-V analog-input device integrates PWM modulators and protection and, when used with external MOSFETs and components, can form the basis of a complete two-channel audio amplifier.

Key specifications include a sink/source current of 0.6/0.5 A, a VCC range of 10-15 V, and a TON /TOFF propagation delay of 325/350 ns. Key features include:

  • Internal clock oscillator
  • Clipping detection
  • Fault reporting output
  • External thermal sensor input
  • On-chip thermal shutdown
  • Programmable over-current protection
  • Programmable dead-time generation
  • Start/stop click reduction

The IRS2052M is packaged in a 48-Lead MLPQ. Pricing begins at US $4.99/ea in quantities of 10,000.
