LM49450SQX/NOPB is a 32-pin stereo audio subsystem combining a 24-bit I2S DAC, Class D speaker drivers, and ground-referenced headphone amplifiers.

Best for

  • Portable stereo audio products requiring speakers and headphones
  • Systems using I2S digital audio and I2C configuration

Avoid if

  • A single-supply-only audio design cannot support the required supply domains
  • The PCB cannot accommodate a 32-pin 5 mm x 5 mm WQFN package

Check before use

  • Speaker impedance and output-power target
  • Headphone sense connection and jack switching
  • MCLK frequency, DAC mode, and charge-pump divider settings
