TPA3116D2 - Filter-Free Class-D Stereo Amplifier

General Description

The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono.

The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB.

Key Features

  • 1 Supports Multiple Output Configurations.
  • 2 × 50 W Into a 4-Ω BTL Load at 21 V (TPA3116D2).
  • 2 × 30 W Into a 8-Ω BTL Load at 24 V (TPA3118D2).
  • 2 × 15 W Into a 8-Ω BTL Load at 15 V (TPA3130D2).
  • Wide Voltage Range: 4.5 V to 26 V.
  • Efficient Class-D Operation.
  • >90% Power Efficiency Combined With Low Idle Loss Greatly Reduces Heat Sink Size.
  • Advanced Modulation Schemes.
  • Multiple Switching Frequencies.
  • AM Avoidan.
