Q: DCC的DAC输出电压范围是多少？

A: 是0.5v

请参考https://www.ti.com.cn/cn/lit/ds/ ... %252Fcn%252FDAC5672第18页：

Applying a 20-mA full-scale output current would lead to a 0.5-VPP output for a 1:1 transformer
and a 1-VPP output for a 4:1 transformer. In general, the 1:1 transformer configuration will have slightly better
output distortion, but the 4:1 transformer will have 6 dB higher output power
