Product Overview

The TPA3123D2EVM is a TPA3123D2 evaluation module consists of a single 25W, class-D, stereo audio power amplifier complete with a small number of external components mounted on a circuit board that are used to directly drive speakers with an external analog audio source as the input. The TPA3123D2 can drive stereo speakers as low as 4Ω . The efficiency of the TPA3123D2 eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20dB, 26dB, 32dB, 36dB. The patented start up and shut down sequences minimize pop noise in the speakers without additional circuitry.
  • 25W/ch into a 4Ω load from a 27V Supply
  • 20W/ch into a 4Ω load from a 24 V Supply
  • Operates from 10V to 30V
  • Efficient class-D operation eliminates need for heat sinks
  • Four selectable, fixed gain settings
  • Internal oscillator (No external components required)
  • Single ended analog inputs
  • Thermal and short circuit protection with auto recovery
  • Space saving surface mount 24 Pin TSSOP Package
  • Pin to pin compatible with TPA3120D2
It is important to operate this EVM within the input voltage range of 10V to 30V and the output voltage range of 0V to 30V. Exceeding the specified input range may cause damage to the EVM.
