The EVC Click Board™ is a six-channel digital volume controller, equipped with an integrated electronic volume control circuit, which can be controlled over the I2C interface. The PT2258 IC offers six individual input channels, each with an 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 Board™ features very low noise and a high Signal to Noise ratio (SNR) of more than 100dB. A low Total Harmonic Distortion (THD) of 0.005% ensures absolute sound clarity.
