Hello all,
Regarding LTC5589 I/Q input DC bias,
There is an internally generated 1.4V DC bias.
Q1: The datasheet mentions an option to disable the internal bias. How can this be achieved?
Q2: I am using an FDA with a common-mode voltage of 1.65V. What would happen if I connect 1.65V-biased I/Q signals to the modulator inputs? My assumption is that it should be fine due to the 1kΩ resistors between the input and the internal reference, but I would like to confirm.
Thanks
Nir
