MAX9724B - (MAX9724A/B) Stereo Headphone Amplifier

Download the MAX9724B datasheet PDF. This datasheet also covers the MAX9724A variant, as both devices belong to the same (max9724a/b) stereo headphone amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX9724A/MAX9724B stereo headphone amplifiers are designed for portable equipment where board space is at a premium.

Key Features

  • Improved RF Noise Rejection (Up to 67dB Over Typical Amplifiers).
  • No Bulky DC-Blocking Capacitors Required.
  • Low-Power Shutdown Mode, < 0.1µA.
  • Adjustable Gain (MAX9724A) or Fixed -1.5V/V Gain (MAX9724B).
  • Low 0.02% THD+N.
  • High PSRR (80dB at 1kHz) Eliminates LDO.
  • Integrated Click-and-Pop Suppression.
  • 2.7V to 5.5V Single-Supply Operation.
  • Low Quiescent Current (3.5mA).
  • Available in Space-Saving Packages: 12-Bu.

www.DataSheet4U.com 19-3597; Rev 3; 3/07 60mW, DirectDrive, Stereo Headphone Amplifier with Low RF Susceptibility and Shutdown General Description The MAX9724A/MAX9724B stereo headphone amplifiers are designed for portable equipment where board space is at a premium. These devices use a unique, patented † DirectDrive™ architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. The MAX9724 suppresses RF radiation received by input and supply traces acting as antennas and prevents the amplifer from demodulating the coupled noise. The MAX9724A offers an externally adjustable gain while the MAX9724B has an internally preset gain of -1.5V/V.
