Created on Monday, 13. March 2006.

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.)
