Mikroelektronika MIKROE-3271 AudioAmp 4 Click Board, LM4860M 1W Audio Amplifier, GPIO/PWM

Technical description of the product (MIKROE-3271):

The AudioAmp 4 click is a low-power audio amplifier with digital volume control. It is equipped with the LM4860, an audio amplifier IC capable of delivering up to 1W of continuous power to an 8 Ω load. It has a very low total harmonic distortion (THD) of less than 1% over the entire audio spectrum, making it perfectly suited for small boom-boxes, PC speakers, and similar low-power sound reinforcing devices that can be powered by batteries. A high integration level of the LM4860 IC allows an additional circuit for digital signal attenuation to be used, offering 8 different volume levels, selectable over 3 GPIO pins of the mikroBUS™. Ideal for various low power audio systems, home stereo components, computer speakers, and many other similar audio applications that require audio amplification with digitally controlled volume level. Key features include high quality audio output up to 1W of continuous power, good frequency response, low THD and SNR, and digital volume control.
