A balanced stereo input ADC based on the PCM4202 (ADC-PCM4202)

A balanced input stereo input ADC. This is based on the high performance PCM4202 Delta-Sigma ADC. This is hardware controlled only. The differential input stage gives flexibility to connect to a range of single ended and differential audio sources. The input gain can be change through adjustment of the resistors around the input buffers.
