TPA3118D2-Q1 - 100-W and 50-W Class-D Stereo Automotive Amplifiers

Download the TPA3118D2-Q1 datasheet PDF. This datasheet also covers the TPA3116D2-Q1 variant, as both devices belong to the same 100-w and 50-w class-d stereo automotive amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPA311xD2-Q1 devices are automotive stereo, efficient, digital-amplifier power stages for driving speakers up to 100 W into 2 Ω in mono.

The TPA3118D2-Q1 can even drive 2 × 30 W into 8 Ω without a heat sink on a dual-layer PCB.

Key Features

  • 1 Supports Multiple Output Configurations.
  • 2 × 50 W Into a 4-Ω BTL Load at 21 V (TPA3116D2-Q1).
  • 2 × 30 W Into an 8-Ω BTL Load at 24 V (TPA3118D2-Q1).
  • 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 Avoidance.
  • Master and Slave Synchronization.
