    This album contains some images of my TDA1543 DAC.

    It currently has a problems in that it produces proper sound only when the digital volume is low, otherwise it distorts.

    The measurements in the diagrams are recordings of a 440 Hz sine wave, showing the problem when the (digital) volume is increased ever-so-slightly. (Volume raised by one step from 11 to 12 in the middle of the pictures. Range is 0-40.)
