TPA2005D1 - 1.4-W MONO Filter-Free Class-D Audio Power Amplifier

General Description

The TPA2005D1 is a 1.4-W high efficiency filter-free class-D audio power amplifier in a MicroStar Junior™ BGA, QFN, or MSOP package that requires only three external components.

Key Features

  • 1 1.4 W Into 8 Ω From a 5 V Supply at THD = 10% (Typ).
  • Maximum Battery Life and Minimum Heat.
  • Efficiency With an 8-Ω Speaker:.
  • 84% at 400 mW.
  • 79% at 100 mW.
  • 2.8-mA Quiescent Current.
  • 0.5-μA Shutdown Current.
  • Capable of Driving an 8-Ω Speaker (2.5 V ≤ VDD ≤ 5.5 V) and a 4-Ω Speaker (2.5 V ≤ VDD ≤ 4.2 V).
  • Only Three External Components.
  • Optimized PWM Output Stage Eliminates LC Output Filter.
  • Internal.
