Texas Instruments TAS5828M | Demoboard TAS5828M Evaluation Module
50-W stereo, digital input, high-performance, closed-loop, Class-D, with integrated audio processor
Overview
| Topology | Class D Audio Amplifier |
Description
The TAS5828MEVM showcases the latest TI digital input Class-D closed loop amplifier. The TAS5828M is a digital input stereo high-efficiency Closed-Loop Class-D audio amplifier with an advanced Hybrid-Pro algorithm to improve system efficiency and reduce heat without clipping distortion. The TAS5828EVM is a stand-alone EVM, which has an optional battery power supply input with LM5155 boost or external power supply input bypassing the LM5155 boost, USB control via PurePath Control Console 3 (PPC3), and flexible audio input options. The TAS5828MEVM also can be configured using the Hardware control mode that supports setting switching frequency, analog gain, BTL/PBTL mode and Cycle by Cycle current limit threshold through pinconfiguration. This mode is especially designed to eliminate end system software driver integration efforts.
Features
- TAS5828M Hybrid-Pro algorithm for audio envelope tracking
- Integrates LM5155 boost to provide customer system design reference
- Default system configuration: 5 V battery input, boost to max 16 V power rail based on audio envelope tracking
- Flexible TAS5828M Hybrid-Pro output (HPFB pin) to customer system board capability
- 96-kHz Input Sample Rate Support
- Operates in BTL or PBTL
- Provides flexible input signal routing (USB, Analog, Optical and external I2S)
- Demonstration, Evaluation and Development environment via the PurePath Console 3 software (GUI)
- Optional Hardware control mode to set switching frequency, analog gain, BTL/PBTL mode and Cycle by Cycle current limit through pin configuration
Typical applications
- Soundbars and subwoofers
- Battery-powered speaker, Wireless, bluetooth speakers, Heat or efficiency senstive audio system
