CURRENT OUTPUT CIRCUIT

摘要

Provided is a current output circuit 1 including a pseudo sine wave separation circuit 11 that separates a pseudo sine wave represented by a digital code Din into two pseudo half-waves represented by digital signals D1 and D2, a DA converter 113 that converts the pseudo half-wave represented by the digital signal D1 into an analog half-wave signal V1, a DA converter 114 that converts the pseudo half-wave represented by the digital signal D2 into an analog half-wave signal V2, and a voltage-current conversion circuit 12 that converts voltages of the half-wave signals V1 and V2 into currents and outputs a current Iout obtained by combining the currents.

1. A current output circuit comprising:
a separation circuit that separates a digital pseudo sine wave into first and second digital pseudo half-waves; a first DA converter that converts the first digital pseudo half-wave into a first analog half-wave signal; a second DA converter that converts the second digital pseudo half-wave into a second analog half-wave signal; and a voltage-current conversion circuit that converts voltages of the first and second half-wave signals into currents and outputs a current obtained by combining the currents.
