Features

AI Translation
  • Integrated inverting boost converter
  • 2.7V to 5.5V single-supply operation
  • 16VP-P output voltage swing, ideal for driving ceramic speakers
  • Maintains output voltage swing as battery voltage drops
  • Click-and-pop-free operation
  • Compact, thermally efficient 5x4 WLP package (2.5mm x 2mm)
  • Mono Class G power amplifier with integrated inverting boost converter
  • Designed for driving the high capacitance of ceramic/piezoelectric speakers
  • Inverting boost converter typically delivers up to 400mA peak output current, enabling constant 16VP-P output across 2.7V to 5.5V supply voltage range
  • High-performance efficiency maximizes battery life
  • Proprietary output stage with higher efficiency than Class AB devices and without the EMI issues common to Class D amplifiers
  • Ideal for delivering the high output voltage swing required to drive ceramic/piezoelectric speakers
  • Features fully differential inputs and outputs, comprehensive click-and-pop suppression, shutdown control, and soft-start circuitry
  • Fully specified over extended temperature range of -40°C to +85°C
