摘要：It is digital/the output electric current of analog converter can generate it istwo-way be particularly useful digitally coded audio signal direct conversion. The
converter be by multiple element circuits (53 57), one in digital coding, each circuit be it isequal in magnitude by a pair of of current source (1,2), it is contrary. Each unit is a fourbridge circuit devices (3,4,5,6), can be by a data bit and supplement, the value of the datapoint after the electric current output reversion for making electric current pass throughbattery. The output bit of cell is in parallel, is binary mode to current source scale, isresponsible for each on the cell of less than half of battery current. In a preferredembodiment, the electric current of current source is by two graduation network resistorR -2R(46,47) adjusts your two current reference sources (40,41). Two are preferablyarrived another with reference to correlation and pass through a feed circuit
(64,65,66,68). Reference (41) can modify (another is automatically tracked) as controlamount.
