TPA3132D2 - Filter-Free Class-D Stereo Amplifier

Download the TPA3132D2 datasheet PDF. This datasheet also covers the TPA3131D2 variant, as both devices belong to the same filter-free class-d stereo amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPA313xD2 are efficient, stereo digital amplifier power stages for driving speakers with up to 2x42W/4Ω peak power.

TPA3131/32D2 operates heatsink-free with cooling to PCB through the bottom side PowerPAD™ with sustained output power from 2 × 4 W / 8 Ω (TPA3131D2) to 2 × 25 W / 8 Ω (TPA3132D2).

Key Features

  • 1 Supports Multiple Output Configurations.
  • 2 × 4 W into a 8-Ω BTL Load at 7.4 V (TPA3131D2).
  • 2 × 25 W into a 8-Ω BTL Load at 19 V (TPA3132D2).
  • Wide Voltage Range: 4.5 V to 26 V.
  • Automotive Load-Dump Compliant.
  • Efficient Class-D Operation.
  • >90% Power Efficiency Combined With Low Idle Loss for Heat Sink free Operation.
  • Advanced Modulation Schemes.
  • Multiple Switching Frequencies.
  • AM Avoidance.
  • Master.
