PA3428 - 2W STEREO AUDIO AMPLIFIER

General Description

As a stereo audio speaker which is operating on a single 5V supply, the UTC PA3428 is capable of delivering 2W of output power per channel into 4Ω loads with less than 1% THD+N.

Way of two terminals (GAIN0 and GAIN1) can configured and control the amplifier gain.

Key Features

  • Internal Depop circuitry.
  • Output power at 1% THD+N Supply voltage:5V Delivering 2.0W into a 4Ω load Delivering 1.2W into a 8Ω load.
  • Tow mode: Bridge-tied Load (BTL), Single-ended (SE).
  • Stereo input signal.
  • Fully differential input.
  • Gain control Internally.
  • Differential Input fully Lead-free: PA3428L Halogen-free: PA3428G.
