TPA4861 - 1-W MONO AUDIO POWER AMPLIFIER

General Description

The TPA4861 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average power into an 8-Ω load at 0.2% THD+N from a 5-V power supply in voiceband frequencies (f < 5 kHz).

Key Features

  • 1-W BTL Output (5 V, 0.11 % THD+N).
  • 3.3-V and 5-V Operation.
  • No Output Coupling Capacitors Required.
  • Shutdown Control (IDD = 0.6 µA).
  • Uncompensated Gains of 2 to 20 (BTL Mode).
  • Surface-Mount Packaging.
  • Thermal and Short-Circuit Protection.
  • High Supply Ripple Rejection Ratio (56 dB at 1 kHz).
  • LM4861 Drop-In Compatible D.
