The MAX9768 evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that demonstrates the capabilities of the MAX9768 mono 10W Class D speaker amplifier with volume control. The MAX9768 EV kit also includes Windows® 98SE/2000/XPcompatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX9768.

The MAX9788 evaluation kit (EV kit) is a fully assembled and tested PCB that uses the MAX9788 Class G amplifier to drive a bridge-tied-load (BTL) ceramic speaker in portable audio applications.

The EPC9106 demonstration board is a reference design for a 150 W / 8 Ω Class D audio amplifier. The demonstration board uses a Bridge-Tied-Load (BTL) design, composed of four ground-referenced Half-Bridge Output Stages. This architecture and topology allows scalability and expandability.

The IRAUDAMP7D reference design is a two-channel Class D audio power amplifier that features output power scalability. The IRAUDAMP7D offers selectable half-bridge (stereo) and full-bridge (bridged) modes. This reference design demonstrates how to use the IRS2092 Class D audio driver IC, along with IR’s digital audio dual MOSFETs, such as IRFI4024H-117P, IRFI4019H-117P, IRFI4212H-117…

The IRAUDAMP10 demo board is a reference design which uses only one IC (IRS2052M) to derive appropriate input signals, amplify the audio input, and achieve a two-channel 280 W/ch (4Ω, THD+N=1%) half-bridge Class D audio power amplifier.

The TAS2552 is a high efficiency Class-D audio power amplifier with advanced battery current measurement and an integrated boost converter. It drives up to 3.5 W into an 8Ω speaker. The built-in boost converter generates the Class D amplifier supply rail. This boosted supply rail provides louder audio than a stand-alone amplifier directly connected to the battery.

The STEVAL-CCA040V1 demonstration board is designed using the STA540SAN dual/quad class AB power amplifier assembled in a Clipwatt 15 package.

The STEVAL-CCA042V1 is a demonstration board designed for the evaluation of the TDA7491HV dual BTL class-D audio amplifier. This application note provides the board specifications and a quick-start list for standalone operation. Also included are the schematic, printed circuit board layout and bill of material.

The SSM2518 is a digital input, Class-D power amplifier that combines a digital-to-analog converter (DAC) and a sigma-delta Class-D modulator.

The TPA3221EVM HD-Audio evaluation module demonstrates the TPA3221 integrated circuit from Texas Instruments. TPA3221 is an ultra-low idle-loss Class-D amp which keeps your system cooler and your battery playing longer while supporting 100kHz high resolution audio and features single-rail power supply support, gain settings, mute, and integrated protection.
