NS4890C - 2.4W Mono Class AB audio amplifier

Description

NS4890C is a class AB bridge output audio amplifier.

Its application circuit is simple and only a few peripheral devices are needed.The output does not require external coupling capacitors or lifting capacitors and buffering networks,it is more suitable for portable systems.

Features

  • Voltage range:3.0V-5.0V.
  • Output power: 1.56W@RL=8Ω/THD+N=10%.
  • Leakage current in shutdown mode:1uA(typical).
  • The SD pin is used for low level control to enter shutdown mode.
  • Stable unity gain.
  • External feedback resistor and input resistor, adjustable gain.
  • MSOP8 package. 2.
