DS125DF111: The following figure shows the input and output of DS125DF111 are correct or not?

Kevin cao

Part Number: DS125DF111

For some reason, when laying out the PCB,i need to set the input and output of DS125DF111 as shown in the figure, the input is OUT_P --- INA- \ OUT_N ----- INA+, and the output is also OUTA- ---- TD+ \OUTA+ ----- TD-, my question is, is it possible to reverse the input and output? Do you need to inverting the polarity in the configuration (0x1f 0f bit7)?

TKS!

Hi Kevin,

It is possible to the reverse the input and output, similar to what you have in your schematic. By default, there is no polarity switch in the device. For your current schematic, this means that your OUT_P polarity would be the same as TD+. If you would like to invert the polarity, then yes you can do this through the register write. To invert polarity, write a 1 to 0x1F[7].

Thanks,
Drew
