MAX9728B - Stereo Headphone Amplifiers

Download the MAX9728B datasheet PDF. This datasheet also covers the MAX9728A variant, as both devices belong to the same stereo headphone amplifiers family and are provided as variant models within a single manufacturer datasheet.

Features

  • No Bulky DC-Blocking Capacitors Required.
  • Low-Power Shutdown Mode, < 0.1µA.
  • Adjustable Gain (MAX9728A) or Fixed -1.5V/V Gain (MAX9728B).
  • Low 0.02% THD+N.
  • High PSRR (80dB at 1kHz) Eliminates LDO.
  • Integrated Click-and-Pop Suppression.
  • 4.5V to 5.5V Single-Supply Operation.
  • Low Quiescent Current (3.5mA).
