The PT2258 IC offers six individual input channels, each with the attenuation range between 0 and -79dB, in 1dB steps. This chip requires a minimum number of external components, simplifying its implementation in a wide range of modern audio application. As an audio circuit, EVC click features very low noise and high Signal to Noise ratio (SNR) of more than 100dB. Low Total Harmonic Distortion (THD) of 0.005% ensures absolute sound clarity. EVC 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.
