2x30W Amp Click Board

2x30W Amp click is a class-D audio amplifier with a tremendous output power, considering its size and lack of huge heatsinks, usually associated with the audio amplifiers. This is due to the fact that the efficiency of the amplifier IC is quite high (greater than 90%), featuring the efficiency boost mode, which dynamically reduces the current ripple of the external LC filter and current in idle mode. The integrated self-protection circuits include overvoltage, undervoltage, and overtemperature protection, output DC offset detection, as well as the short circuit detection, with the error reporting feature, via the dedicated pin.

2x5W AMP Click Board

The 2 x 5W Audio Amplifier Click Board functions as an amplifier and features the TDA7491LP 2x5-watt dual BTL class-D audio amplifier. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over the following pins on the MikroBUSline: AN, RST, CS, PWM, INT.

The 2 x 5W AMP click features a 3.5mm input jack and four output screw terminals for connecting passive speakers.
Note: In order to achieve full 2x5W output power, keep in mind that you need to supply enough current to the chip. This is achievable with the EXT PWR header, but you need to switch over the AMP VCC to the left position.

AudioAmp 2 Click Board

Audio Amp 2 click is a highly efficient class D audio amplifier, using the TDA7491, a dual BTL class-D audio amplifier IC, capable of delivering up to 20W to 8Ω load. This amplifier IC features high-efficiency output stage drivers and clever design, allowing it to deliver a reasonably high power to the connected speakers, using only GND polygon on the PCB for heat dissipation. In the BTL topology, the output DC blocking capacitors are not required. This allows for simpler design and lower power losses, especially with no input signal. The TDA7491 amplifier IC is equipped with a set of protection features, that allow reliable operation.

AudioAmp 5 Click Board

Audio Amp 5 Click is a stereo audio amplifier, capable of delivering up to 10W per channel with the 8Ω load. It is based on the TPA3138D2, a class-D integrated amplifier, which utilizes a highly efficient switching scheme. With about 20mA in idle mode, it allows for longer operation and improved thermal performance, making it a perfect choice for various battery-powered applications. Advanced EMI Suppression with Spread Spectrum Control allows using ferrite bead filters instead of bulky inductors, still maintaining the required EMC levels. The TPA3138D2 IC is equipped with a set of protection features, allowing a reliable operation.

Audio Amp 5 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
