DA converter classification

DA converter classification
http://www.siliconray.com/audio-amateur/dac.htmlDA converter circuit inside the form without too much difference, the output is general current or the voltage, can make multiplication of classification. Most DA converter by resistor and n current switch (or voltage switch) constitutes. According to the digital input value switch, produce in proportion to the input current (or voltage). In addition, also have to improve the accuracy and the constant current source into the internal components. Generally speaking, because of the current switch switch small error, mostly using current switch type circuit, current switch type circuit output generated current if directly, it is current output type DA converter, if the current 椀 Samuel coffin?
