We are using ADA4932 buffer as Differential to Single-ended converter. We have a few queries.

 

  • Do you have any preferred circuit.#Below is our configuration. Is it ok 
   
  • Do we need to provide a matching load at the unused output pin(OUT-) or Is it okay to leave it floating? As of now, we have terminated OUT- pin to GND via 100 Ohm. Is this 100 Ohm required?
  • As of now the gain of the amplifier is 4 and we planned to source sine wave of frequency 1Mhz to 80 MHz. Do you see any concern regarding the bandwidth?
