MikroElektronika Audio Amp 4 Click GPIO, PWM MIKROE-3271

AudioAmp 4 click is a low-power audio amplifier with a 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, which makes 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™. AudioAmp 4 click is supported by the mikroSDK compliant library, which includes functions that simplify software development. The Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ slot.
