ADL5205 and ADL5206_OP1dB

Hi Doolpung

We are working on the ADL5206 characterization at the moment. I guess you will use ADL5205/06 with an ADC for IF sampling. What is the input impedance (differential and single ended) and what is the input common mode voltage of the ADC? 

Hi,

Pleas refer to the following picture.

and if the common mode voltage of ADL5567,ADL5206 and ADC/DAC is different, how can we adjust the voltage value?

Thank you.

Hi Josh,

Please refer to Fig.51 of ADL5567 datasheet. Its supply voltages are shifted to +3.3V and -2V. VCOM pins could be driven externally to 0.7V, thus matching with ADC/DAC interface.
