Hi,

I am connecting output of TX810 at the input of AD8331. Just as shown in page 9 figure 13 (T/R switch + amplifier switch).

And  the signal from my TX810 is in nano amps, 17Mhz received signal from capactive based ultrasonic sensor.

 

Could you please clarify the following doubts.

1.Can i use AD8331 as a transimpedance amplifier?

2.Is it okay to connect the output of the LNA to a oscilloscope and leave the VGA part not enabled?

 

Thanks in advance,

Livingstone Arjunan.
