Mikroe MIKROE-3271 AudioAmp 4 Click
Mikroe MIKROE-3271 AudioAmp 4 Click is a low-power audio amplifier with digital volume control. This Mikroe click includes the LM4860 audio amplifier IC capable of delivering up to 1W of continuous power to an 8Ω load. The MIKROE-3271 features a very low Total Harmonic Distortion (THD) of less than 1% over the entire audio spectrum. The LM4860 IC is highly integrated and allows an additional circuit for digital signal attenuation to be used. This IC offers eight different volume levels that are selectable over 3 GPIO pins of the mikroBUS™.
The MIKROE-3271 click also incorporates the CD74HC4051 high-speed CMOS logic analog mux/demux from Texas Instruments. This click offers a flat audio characteristic, low THD, noise levels over the entire audio spectrum range, and digital volume control. These features make the AudioAmp 4 click an ideal solution for rapidly developing applications when a quick and simple low-power audio signal reinforcement is required.
