Digital-to-analog converter with current source centrally located between a plurality of current mirrors

摘要: A D/A converter has one single input transistor used in common with a plurality of output transistors to together form current mirrors, and decoder serves sequentially select the mirrors response digital input, causing generate corresponding analog from currents selected ones mirrors. The commonly is centrally located respect such that difference between maximum minimum distances, or parasitic resistances, reduced conversion characteristic can be improved.
