Description
Sound card for Sparky and Raspberry with two converters of C/A PCM5142 with a built-in DSP processor. It has 4 outputs which can work in the 2.0, 2.1 or 2.2 system (with or without subwoofer). Programming of the outputs is made via the applicationPurePath.
The device separates the digital and analog part by application of different LDO regulators. On the analog side, applied were regulators LDO LT3042 which are characterized by very low noise and high PSRR ratio. On the digital side, applied was cheaper version. The module has 4 built-in LDO regulators.
