Hi, can ADL5205 be used as single-ended input mode?
I want to dc-coupled and single-ended input to the chip , what shell i do for the front-end of ADL5205?
The ADL5205 can be DC coupled. The single-ended input and outputs need to have a common mode voltage of +2.5V, assuming the amplifier is using a +5V supply.
For the single-ended input configuration, the input should be the Vin+ and the Vin- pin should be tied to ground through a series ac coupling cap of 0.1uF and a series resistor of 34ohms. Additionally, the Vin+ pin should have a 100ohm termination to ground as well. Assuming the source is 50ohms driving that pin.
Hope this helps.
Thank you for your reply!
