Texas Instruments TAS5827EVM Amplifier Evaluation Module (EVM)
Texas Instruments TAS5827EVM Amplifier Evaluation Module (EVM) helps designers evaluate the operation and performance of the TAS5827 digital-input closed-loop Class-D amplifier. The TAS5827 is a stereo high-performance closed-loop Class-D amp with low power dissipation and advanced audio processing. The GUI called PurePath™ Control Console 3 interfaces with USB to the evaluation module. The Texas Instruments TAS5827EVM has optical SPDIF inputs, I2S, TDM, and audio inputs through the USB interface.
Features
- The integrated DSP of the TAS5827 enables Class-H envelope tracking, eliminating the need for the development of complex tracking software or an external microcontroller
- Onboard LM5155 boost to evaluate Class-H efficiency performance and provide customer system design reference
- Default system configuration: battery input, boost to max 20V power rail based on audio envelope tracking
- Optional hardware control mode to set switching frequency, analog gain, BTL/PBTL mode, and Cycle by Cycle current limit through pin configuration
- Provides flexible input signal routing (USB, analog, optical, and external I2S)
- Demonstration, evaluation, and development environment via the PurePath Console 3 software (GUI)
Applications
- LCD TV, OLED TV, Mobile smart TV, Laser TV, Mobile smart TV
- Smart speakers, Smart displays, sound bars, wireless speakers
- Notebook PC, desktop PC/motherboard
- Piano, keyboard, synthesizer, professional speaker systems
- Professional conference systems, enterprise projectors
