<p>The invention provides a balanced / unbalanced signal output circuit which selectively switches balanced output and unbalanced output with simple structure, and is free of waste. When the balanced / unbalanced signal output circuit is in a balanced output, an analog normal phase signal and an analog inverse signal are respectively generated through a D/A converter (10, 12), and are output from a balanced HOT terminal and a balanced COLD terminal through switching switches (20,22). When the circuit is in a unbalanced output, the analog normal phase signal is respectively generated through a D/A converter (10, 12) and output from an unbalanced terminal through switching switches (24,26).</p> |
