PURPOSE: An output device and a testing device are provided to make smaller composition of the output device, thereby reducing total manufacturing cost. CONSTITUTION: A plurality of maintenance parts(24) is respectively corresponding to a plurality of current sources(22). The maintenance part maintains assignment voltage which is assigning the current flowing in the corresponding current source. A DAC(30) for establishment successively generates the assignment voltage. A supply port(32) successively supplies the assignment voltage to the corresponding maintenance part. A corresponding output device is a DA conversion device. The output device transmits a current according to input data received from the outside to an output end. |
