AudioAmp 6 click

Audio Amp 6 click is a mono/subwoofer audio amplifier, capable of delivering up to 18.5W per channel with the 4Ω load. It is based on the TPA3138D2, a class-D integrated amplifier, which utilizes a highly efficient switching scheme.

Software Support

We provide a library for the AudioAmp6 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for AudioAmp6 Click driver.

Standard key functions :

Example key functions :

Examples Description

The demo application displays the volume change using AudioAmp 6 click.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Select mode and sets output on the enable state.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
AUDIOAMP6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
audioamp6_init( &audioamp6, &cfg );
log_info( &logger, "---- Start control AudioAmp 6 click ----" );
}

Application Task

Changes the gain settings ( 20dB - 26dB )

void application_task ( void )
{
// Task implementation.
log_printf( &logger, ">> Set gain 20 dB \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, ">> Set gain 26 dB \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}

Note

Sets the input voltage from 3.5V to 14.4V.

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.AudioAmp6

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
